Is the KO3 good on-road?

Yes, but it feels heavy. Dry grip is stable (140-ft stop, 0.72 g), though steering response is slower than road-biased A/Ts.

How does the KO3 handle rain?

Wet braking is a weak point (~184 ft, 0.46 traction). It stays straight under load but needs extra stopping distance.

Is the KO3 good in snow?

Strong in loose snow (72.3-ft stop, 46.4-ft launch), but less convincing on packed or plowed surfaces.

How does the KO3 perform on ice?

It stops in ~46.2 ft. Predictable slide, but longer distances mean caution is needed in icy climates.

Is the KO3 good off-road?

Yes — with 9.5 dirt, 9.5 sand, 9.2 mud, 9.5 rock, it’s one of the toughest A/Ts, built for rocky, muddy, and desert terrain.

How comfortable is it?

Comfort is firm (~7.5/10). Starts quiet, but hum builds over time, especially if rotations are missed.

How long does the KO3 last?

Typically 45–55k miles with proper rotations. Durable compound resists chipping but grows noisy if neglected.

Which vehicles fit it best?

Best for ½-ton and HD trucks used in rocky, dry, or trail-heavy regions. Overkill for SUVs or rain-heavy commutes.

Updated: November 11, 2025 by Emrecan Gurkan Leave a Comment

The Toyo Open Country R/T Trail is no ordinary rugged terrain tire; it’s a game-changer for both on and off-road enthusiasts. You might recall Toyo’s first rugged terrain tire, the Open Country R/T. While it leaned more towards a mud-terrain feel, it did have its limitations, especially in winter and wet conditions. But here’s the scoop: the new Open Country R/T Trail is designed more like an all-terrain tire, offering exceptional on-road performance. And here’s a noteworthy point—it’s proudly made in the USA! In this in-depth exploration, I’m going to delve into why the Toyo Open Country R/T Trail is poised to take the lead in the rugged terrain tire market. Let’s dive right in!

Quick Look

Toyo Open Country R/T Trail

Tested Rating: 8.1/10

From my point of view as a former Bridgestone engineer, the Toyo Open Country R/T Trail is an exceptional choice for drivers who value stability and performance. Built for heavy-duty pickups, it delivers an unmatched ride despite its aggressive design. While it lacks the 3PMSF marking—which can slightly affect wet performance in colder temps below 7°C (45°F)—it still stands out as a top performer in wet conditions. Off-road is where it truly proves its worth: offering relentless grip on dirt, outstanding traction on rocky surfaces thanks to its durable compound and rim protection, and mud performance that surpasses typical all-terrain tires so you won’t get stuck easily. It also excels in sand, reducing the risk of bogging down in soft terrain. While it may not have the longest lifespan in its class, it delivers impressive longevity with consistent performance on and off-road, making it a highly recommended pick for those who want a tire that blends functionality with rugged aesthetics.

Responsiveness

The Toyo Open Country R/T Trail is more than just a tire with good looks—it’s expertly designed for those who like to push their vehicles to the limit. Curious about the design? Let’s break it down.

Compared to your typical mud-terrain tires, this tire features a tighter tread pattern. Take a closer look at the center, and you’ll notice those larger-than-average tread blocks. What’s clever about this design is that it ensures there’s always a solid grip on the road, providing you with responsive handling.

Now, for those wondering about towing, I’ve got you covered. That unique design with the step-down on the center blocks? It’s not just for aesthetics. It prevents those blocks from shifting, giving your vehicle an extra dose of stability. And here’s the kicker: as the tire wears down, these blocks become even larger, ensuring you have a stable ride throughout the tire’s lifespan.

In a nutshell, the Toyo Open Country R/T Trail delivers unparalleled stability and responsiveness. For all you towing and hauling enthusiasts out there, this tire is a top-notch choice. Highly recommended!

Cornering Stability

When you’re dealing with full-frame SUVs, heavy-duty pickups, and 1/2-ton pickups, cornering stability isn’t just a nice bonus—it’s an absolute game changer. And now, let’s talk about something that’s been on your minds—the sidewalls!

The Toyo Open Country R/T Trail offers different sidewall constructions depending on the tire size you choose. If you opt for the LT metric sizes, you’re in for a treat with 3-ply sidewalls. But even if you go for the P-metric sizes, they come with 2-ply sidewalls, which is still a solid choice, especially if you don’t have towing and hauling in your plans.

Now, here’s the exciting part for those who choose LT sizes: this tire boasts some of the thickest sidewalls you’ll come across. Imagine beefy side biters that deliver exceptional traction. And that’s not all! These side biters are paired with sturdy shoulder blocks, elevating your cornering stability to a whole new level.

In a nutshell, the Toyo Open Country R/T Trail is your trusty companion when it comes to keeping those heavy-duty pickups rock-steady in corners. So, if you’re one of the folks relying on heavy-duty pickups, this tire is an absolute must-consider. Strongly recommended!

Noise and Riding Comfort

At its core, tire noise typically emanates from two primary sources: the air trapped within the tread and the individual lugs making contact with the road.

You might be thinking, “All-terrain tires are bound to be noisy, right?” Well, you’re not entirely off the mark, but here’s the good news—it’s not a fixed fate. There are innovative ways to turn down that volume a notch or two.

Now, the easiest way to reduce tire noise is by decreasing the void area on the center blocks. However, for rugged-terrain tires, that’s simply not an option. They require that space to ensure optimal traction on challenging terrains like mud, gravel, and heavy snow. But here’s where the Toyo Open Country R/T Trail stands out—it strikes a harmonious balance between the worlds of all-terrain and mud-terrain tires. Let’s just say it leans a tad more toward the all-terrain side.

Here’s the game-changing feature: staggered scalloped shoulder blocks. Think of these as the tire’s very own noise-cancellation system, allowing air to flow out smoothly and thereby minimizing that irritating hum.

The Toyo Open Country R/T Trail isn’t finished flaunting its acoustic prowess. The strategic orientation of its substantial lugs enables them to work together in harmony. The result? A ride that feels both quiet and supremely comfortable.

In conclusion, for a tire with such an aggressive design, the Toyo Open Country R/T Trail delivers a surprisingly serene ride experience. Just a heads-up, though: if you inflate them to the maximum PSI, you might hear a gentle hum. But hey, that’s a small trade-off for the killer looks and performance you’ll get in return!

Note from the Expert: For years, choosing all-terrain meant accepting noise—a true compromise for off-road grip. That’s why the question, Are All-Terrain Tires Louder than Highway Tires?, used to have a simple “yes” answer. Now, with the rise of on-road models, the core issue has shifted from noise to overall refinement. To fully understand which side of the comfort spectrum you’re buying into, you need to determine Are All-Terrain Tires Good for Daily Driving?—a question that depends entirely on the tire’s construction, not just the name.

Wet Performance

While talking about the wet performance, we’re not just going to talk about traction. We’re also going to explore the often overlooked yet crucial issue of hydroplaning.

Have you ever felt like your rugged-terrain tire was providing excellent traction, only to suddenly lose grip? Well, that’s often not a problem with traction—it’s hydroplaning in action. In simple terms, your tire is essentially water-skiing on the road surface instead of gripping it. Not an ideal situation!

So, why are we starting with hydroplaning resistance? Here’s a fact to consider: big, wide tires have a tendency to hydroplane, and that’s just a result of physics. The solution? Evacuating water from under the tread as quickly as possible. Toyo tackles this challenge with a straightforward yet effective approach—they channel water straight to the open shoulder blocks. The two distinct circumferential grooves on the Toyo Open Country R/T Trail play a crucial role here. They collect and direct the water out efficiently, thanks to their uniquely angled design. Think of it as the tire’s own rapid drainage system. The bottom line? The Toyo Open Country R/T Trail is seriously impressive when it comes to resisting hydroplaning.

Now, let’s talk about traction in wet conditions. It’s all about how much rubber is in contact with the road and the presence of essential notches. The oriented, generously notched blocks on the Toyo Open Country R/T Trail provide steady contact and a wealth of biting edges. Add to that a 600 A B UTQG rating on its P-metric sizes—matching the laudable Toyo Open Country AT3—and you’ve got a winning formula for solid wet grip.

To sum it up, while the Toyo Open Country R/T Trail excels in wet conditions, here’s a heads-up: it doesn’t come with the 3PMSF mark. So, when the temperature drops below 7°C (or 45°F), its wet performance might take a slight hit. Nonetheless, it remains an excellent choice for wet driving conditions.

Note from the Expert: When it comes to rain, I always emphasize two things: compound grip and water evacuation. You can see the full details in my analysis, but if you take just one thing away, remember that an AT tire’s stiff nature makes achieving top-tier wet performance a constant battle. This is why the question, Are All-Terrain Tires Good in Rain?, requires a nuanced answer that balances tread design against rubber stiffness.

Winter Performance

When we think of rugged-terrain tires, we don’t always picture them conquering snowy landscapes. Why? Mainly because their robust compounds are designed with heavy vehicles in mind. Think more iron and less flexibility.

Now, a quick look at the tire market reveals that many rugged-terrain options don’t feature that coveted 3PMSF (Three Peak Mountain Snowflake) symbol. The reason primarily revolves around concerns related to treadwear. Tires with the 3PMSF badge tend to have about 10% less tread life.

Enter the Toyo Open Country R/T Trail. It also doesn’t boast the 3PMSF mark, which admittedly affects its grip when temperatures drop below 7°C (or 45°F). But wait—does that mean it’s a complete no-go for winter driving? Let’s debunk that idea.

Comparing it to its sibling, the Toyo Open Country AT3, the R/T Trail might lag a bit when it comes to light snow. However, its design, featuring elements like wide lateral zigzag grooves and 4-way tapered notches, ensures that it doesn’t shy away from a snowy challenge. These features provide numerous biting edges, granting it commendable traction in light snow.

But here’s where it truly shines—deep snow. With its towering grooves, unique cavitated pattern, and fierce shoulder biters, the Toyo Open Country R/T Trail emerges as a formidable contender in deeper snow conditions.

Now, let’s address icy roads. Despite its design suggesting great potential, I would advise caution on icy terrains. History has shown us that even the top-tier rugged-terrain tires perform just about average on ice. And average isn’t always reassuring when you’re dealing with icy conditions, both figuratively and literally.

To sum it up, the Toyo Open Country R/T Trail puts on a commendable performance in winter scenarios. However, it’s important to remember that these are not specialized winter tires. As always, when winter strikes, it’s wise to tread (pun intended) with caution.

Note from the Expert: Our discussions often boil down to the core tradeoff. On one hand, you must understand why all-terrain tires are truly effective in deep snow, but not on ice. On the other hand, you face the 3PMSF Paradox—the hidden cost of that badge. The short answer is: The 3PMSF badge certifies traction, but it costs you durability. Dive into our full analysis on the critical 3PMSF rating for severe winter and off-road service, and its hidden costs, before you risk your rig on the trail.

Off-Road Performance

Now, while this tire might have a look that leans towards the all-terrain side, don’t be fooled. Its off-road capabilities surpass many of its all-terrain peers, making it a true trailblazer. And here’s the exciting part: experienced off-road adventurers have tested the Toyo Open Country R/T, so its impressive performance isn’t just a claim—it’s been endorsed by the pros!

On the Trail:

Dirt: On traditional dirt trails, the Toyo Open Country R/T Trail is truly outstanding. It’s everything you hope for with rugged-terrain tires! With its multitude of biting edges, this tire provides relentless grip, making your dirt adventure smoother than ever.

Rocks: If you’re heading into rocky terrains, this tire won’t let you down. Its robust, cut and chip-resistant compound offers solid traction and durability. Plus, with a deep rim protector and muscular shoulder biters, it provides that extra shield for both your rims and sidewalls against those tricky rocky obstacles.

Mud: Muddy paths can challenge most rugged-terrain tires. While the Toyo Open Country R/T Trail’s stone ejectors actively work to fling out the mud, it may struggle a bit in the deepest muck. But don’t worry! When compared to all-terrain tires, it still comes out on top. However, if you frequently tackle deep, sludgy tracks, you might want to consider its sibling, the Toyo Open Country R/T.

Sand: Cruising through sand might seem easy, but the real challenge comes when you stop. However, with the Toyo Open Country R/T Trail, getting stuck is the last thing on your mind. Thanks to its aggressive sidewall biters and cleverly designed staggered and scalloped shoulder blocks, it offers extra traction and keeps the tread clean. So, dune riders, with this tire, you’re in good hands!

Note from the Expert: Every successful day on the trail is about preparation and physics, because tire longevity is earned, not given. Before you even start, you must master the critical link between tire pressure and load range for every rig to maximize your contact patch. Once moving, remember your ultimate off-road armor is your sidewall protection against the inevitable pinch flat. And finally, your traction on the obstacle is dictated by choosing the right aggressive vs hybrid tread pattern for your terrain. Master those three steps, and your rig will be ready for anything.

Tread Life

When it comes to rugged-terrain tires, it’s all about embracing the adventurous spirit while knowing you might be sacrificing some tread life for off-road capabilities. These tires are like the thrill-seekers of the tire world, trading in the stability of a desk job (or in this case, longer tread life) for the excitement of exploring uncharted paths. That’s why you won’t often find a treadwear warranty in this tire category.

Now, let’s talk about the Toyo Open Country R/T Trail. Remember our discussion about its optimized tread design and strategically oriented lugs? Well, those aren’t just fancy terms. They signify a tire that’s been carefully designed for durability.

But here’s the real ace up its sleeve: this tire’s resilience on harsh terrains. Feedback from experienced off-roaders, those trail-blazing experts, reveals minimal wear and tear, even on the most challenging surfaces. That’s a big win!

Now, let’s make some comparisons. Unlike its cousin brand Nitto (sorry Nitto fans!), Toyo has consistently focused on tread life in its tire compounds. I suspect that this tire might have a slightly firmer compound than the Toyo Open Country AT3. But keep in mind, with its impressive traction and considerable weight, it does tend to wear a bit faster.

However, the real star here is the combination of three key features: the three variable pitch pattern, wide lateral zigzag grooves, and the inclusion of stone ejectors. This trio not only extends the tire’s lifespan but also enhances sidewall and tread protection. And the icing on the cake? Toyo backs it up with a confident 45,000-mile treadwear warranty.

In summary, the Toyo Open Country R/T Trail strikes an admirable balance. While no rugged-terrain tire can promise endless longevity, this one certainly offers you a solid run for your money, whether you’re on or off the road.

Warranty

Imagine walking into a store, buying a pair of shoes, and they tell you that you’ll absolutely love them, or you can return them, no questions asked. Well, that’s pretty much the level of confidence Toyo is offering with the Open Country R/T Trail. They back it up with a 45,000-mile treadwear warranty. That’s a whole lot of road trips, off-road adventures, and city cruising. But wait, there’s more! Toyo is sweetening the deal with their limited warranty, like an extended service plan for your favorite pair of boots.

But here’s the real twist: Toyo is throwing down the gauntlet. If, within the first 500 miles or 45 days, these tires don’t make you feel like the ruler of the road, you can bring them back. That’s right, no long-term commitment required. It’s like Toyo’s way of saying, “Take them for a spin, and if you’re not thrilled, we’ve got you covered.”

In plain and simple terms, Toyo is shouting to the world: “We believe in our product, and we’re pretty sure you’ll love it too!” So, if you’re on the fence about getting these tires, just remember, Toyo has your back (or rather, your wheels!).

Sizes

First of all, let’s give Toyo a big thumbs up for their tire versatility – a whopping 47 different sizes! Whether you’re driving a heavy-duty hauler or a beastly monster truck, there’s likely a size that’s just right for you.

Now, let’s talk rim sizes. Toyo covers the entire spectrum, from a nimble 16 inches to a gargantuan 24 inches. So, whether you prefer the stylish look of 22-inch rims or the practicality of 17-inch ones, there’s a size that suits your style.

And here’s where things get technical: the Toyo Open Country R/T Trail comes in P-metric, LT-metric, and flotation sizes. That means there’s a diverse range catering to everyday drivers, heavy-duty truck owners, and occasional off-road enthusiasts.

But if you’re craving even more specific details, you’re in luck. Toyo provides a comprehensive spec sheet and data collection on their product page. It’s like a tech treasure trove for all you tire enthusiasts out there. So, head over to their page, dive in, and explore all the technical goodies they have to offer!

Tire Size Selection: The Basics You Can’t Skip

Even the best tread design can’t rescue a tire that’s built too weak. Back when I was testing tires at Bridgestone, I saw all-terrain models that should’ve performed but fell short — simply because the basics (size, load strength, and speed rating) weren’t matched to the vehicle.

P-Metric vs. LT (Light Truck) Tires

The first step is knowing whether you need LT or passenger tires. LT (Light Truck) tires are built with extra reinforcement and stiff sidewalls, designed for towing, hauling, or off-road use. Passenger (P-metric) tires are lighter, smoother, and tuned for daily comfort and fuel efficiency — but they’ll flex more under load.

Understanding Tire Load Range: XL vs. E-Load

Then comes the tire load index and load range — essentially your tire’s strength rating. Here’s where things split between passenger XL and LT E:

XL (Extra Load) is a passenger tire with reinforced sidewalls. It can handle a bit more pressure (~41 PSI) than a standard SL tire and is perfect for SUVs, crossovers, or light trucks that carry extra gear, passengers, or small trailers. XL tires ride softer and quieter than LT options, making them ideal for daily use.
E Load Range is an LT tire class built with a much thicker casing. E-rated tires can handle far more pressure (up to ~80 PSI) and heavier loads, which makes them essential for ¾-ton and 1-ton trucks towing trailers or hauling close to max capacity. The trade-off is weight, stiffer ride, more road noise, and a small drop in fuel efficiency.

Put simply: XL is for “extra luggage and family,” while E is for “truck bed full of bricks or a car trailer.”

Why the Tire Speed Rating Matters for Safety

Finally, don’t overlook the tire speed rating. It’s not just about top speed — it measures how well a tire handles heat and stress at highway pace. Lower ratings (like S) tend to ride softer and last longer, while higher ratings (H, T) feel more stable and responsive under sharp maneuvers. Heat build-up is the silent killer of tires, and speed rating is your safeguard.

Bottom line: Match your tire’s construction (LT vs P-metric), load range (XL vs E), and speed rating to your vehicle’s demands. Get those right, and everything else — off-road grip, winter traction, comfort — will finally perform the way it was designed to.

Falken Wildpeak R/T Review — Towing Stability & All-Season Traction in 2025

Updated: November 11, 2025 by Emrecan Gurkan Leave a Comment

Falken Wildpeak R/T is a versatile rugged-terrain tire that can be used for different purposes. It’s this rad rugged-terrain tire that’s game for pretty much anything. Whether you’re rocking a heavy-duty pickup, cruising city malls, or hitting those wild off-road trails, this baby’s got you covered. With four distinct designs, there’s something for everyone. Now, I’ve got mad love for the Falken Wildpeak AT3W (seriously, it was dopeee). Super curious to see if the Wildpeak R/T can top that! Let’s dive in and see what it’s got to offer!

Quick Look

Falken Wildpeak R/T01

Tested Rating: 7.9/10

From my standpoint as a former Bridgestone engineer, the Falken Wildpeak R/T is a unique tire that blends maximum traction with long-lasting tread life. Its wet and dry performance is strong, and it shows impressive stability when towing or hauling, making it a dependable choice for work as well as play. Even though it lacks the 3PMSF rating, its winter performance is above average, giving drivers confidence in light snow and cold conditions. Worth noting, the aggressive tread pattern does produce a noticeable hum, but that’s the trade-off for the traction and toughness it brings to the table.

Dry Performance

Dry performance is much more important for rugged-terrain tires because, besides dry traction, it also contains handling features like cornering stability and responsiveness.

It’s no surprise that Falken Wildpeak R/T is a great tire regarding dry traction. However, regarding handling, things are a bit complicated for this tire.

When I was studying this tire, I saw so many people complaining about balancing issues and vibration. I actually going to blame Falken for this because there isn’t enough information about their specifications.

First of all, this is a versatile tire. It has 4 different sidewall stamps (Standart, HD, Duraspec, and HD Duraspec). Choosing the right spec is crucial for better handling.

If you’re looking for a 3-ply sidewall and solid cornering stability, you better go with HD specs. Standard and Duraspec don’t offer a 3-ply sidewall.

If you’re not doing towing or hauling, I mean if you’re a Jeep owner, you better follow standard specs. These specs are less heavier which makes them easier to balance and more responsive. Though worth reminding, that means better on-road manners but slightly worse loose-ground traction.

If you mostly do towing or hauling, then HD spec is better for you. This spec is slightly heavier but that means it has a durable and solid internal structure that increases your stability in towing and hauling applications. This spec also has higher tread depth which makes them better on loose ground.

Then it comes to Duraspec ones. These are only available on load range C. I think they are the best ones for 50% on %50 off-road users. Not great for working trucks but perfect for severe off-road conditions.

Then the masterpiece HD Duraspec ones, are the stiffest and most durable ones. They’re great for working trucks. Sidewall durability and chipping resistance are great but I don’t recommend them for aggressive or long-distance drivers.

In summary, if you can find the right size for you Falken Wildpeak R/T provides unique cornering stability and dry traction. Though, Wildpeak R/T is generally heavy tire. Expecting a quick steering response is a bit utopic for me.

Note: The people who are complaining about balancing issues generally also complaining about tire dealers and most of them said that Discount Tire helps them a lot! You can watch the below video for more.

Wet Performance

The wet performance of rugged terrain tires generally falls short because it’s related chiefly to the compound stiffness and the rubber amount on the ground.

In this case, the UTQG rating is the most critical metric that helps us to measure compound stiffness. However, announcing the UTGQ metric isn’t mandatory for LT metric tires.

So, the UTQG rating isn’t an option for us. In that case, I’m going to put my previous experiences on Falken tires.

I don’t know what are they doing but Falken is making insane compound when it comes to traction. Manufacturers tend to follow what works. Regarding Falken, it’s compound.

After a couple of phone calls and deep research, I find out that Falken uses a similar formula on Falken Wildpeak R/T. It’s sticky as Falken Wildpeak AT3W’s one. Well, it’s of course it’s a just bit stiffer because these tires make for heavier vehicles and have more biting edges.

Besides that, unlike other rugged terrain tires, this one has more sipes on the tread which is great for traction matters.

My only concern is the sipes on the center aren’t full-depth. Well, this increases the stability of the tire but might decrease the wet traction in time.

Overall, Falken Wildpeak R/T provides unique wet traction. Besides that, due to its wide shoulder grooves and siped pattern, it provides reliable hydroplaning resistance.

Winter Performance

Winter traction of rugged-terrain tires is quite complicated because even though these aggressive tires offer deep snow traction, they sometimes fall short regarding light-snow traction.

In this case, most of us are looking for a 3PMSF marking but it’s not popular among the rugged terrain tires because these tires are made for big and heavy trucks. 3PMSF marking means at least 10% fluffy compound, hence, at least 10% less tread life.

So, first of all, the performance of this tire is going to decrease below 7 Celcius degrees (or at 45 Fahrenheit). However, this guy has something most rugged terrain tires don’t have. Center lug siping.

The siping density of this tire is great for a rugged terrain tire. Besides that, these are heavy tires that can create a lot of force on the road.

I’m not going to say it’s going to be perfect on slush or light snow, though, it’s going to be great on deep snow because of its deep tread and very aggressive sidewall biters.

In my point of view, Falken Wildpeak R/T is going to be a strong competitor among rugged terrain tires regarding winter performance. Still, if winter performance is your priority, I recommend going with Falken Wildpeak AT3W or any other 3PMSF-marked all-terrain tires.

Riding Comfort

When I look at the Falken Wildpeak R/T 01, I see mud-terrain tire lugs. But these lugs are closer. So, you might expect a rough ride. Of course, this tire offers a rough ride compared to all-terrain tires. In that case, the real question is ‘Is it bearable?’. Definitely!

The design of Falken Wildpeak R/T holds these lugs always on the road. Hence, you feel way much better riding feeling. Think about Nitto Ridge Grappler, it offers an extremely smooth ride for rugged-terrain tires because of its compact center pattern.

Besides that, these big and tectonic tread blocks have a step-down feature that minimizes block squirm. This feature increases the stability of the tire, especially while towing or hauling.

Overall, Falken Wildpeak R/T offers a relatively smooth ride. Though, if you’re looking for a rugged-terrain tire, probably riding comfort isn’t your priority.

Road Noise

First of all, there is no way that you can find a rugged terrain tire that isn’t humming. So, keeping your expectation at a mediocre level is going to be better.

Since each block of Falken Wildpeak R/T is on the road, this reduces the noise significantly. Hence, this tire performs like an All-terrain tire instead of the mud-terrain tire.

However, you still need maximum traction on the loose ground. For this reason, this tire has aggressive and voided outer tread blocks (shoulder blocks), and the noise you hear is mostly created by these void areas.

The good thing is these shoulder blocks are scalloped which reduces the noise because it decreases the air inside of the tread can be thrown out more easily.

In summary, Falken Wildpeak R/T isn’t quiet as a church mouse but it offers a quiet ride for a rugged-terrain tire.

Treadwear

Treadwear is highly important for rugged-terrain tires because these tires mostly work in severe conditions or under heavy loads. So, they tend to wear quickly.

Even though Falken offers 50,000 miles treadwear warranty for a Wildpeak R/T, the real longevity you’ll see probably going to be different.

Different trucks and different driving conditions affect the mileage you get a lot.

So, the only thing I can definitely say is that Falken Wildpeak R/T is going to wear evenly. Besides that, its compound is highly rigid. It even doesn’t have a 3PMSF.

Overall, if you chose the right spec and be careful about the load range and speed index, you’ll get at least 50,000 miles with this tire.

Note: Most people say that this tire is wearing like an all-terrain tire which means that it offers great wearing.

Getting maximum wear life from a tire is related to you as well as your tire,

Off-Road Performance

Rugged-terrain tires are meant to provide off-road traction. For this reason, these tires have aggressive shoulder biters, deep tread, and big spaces between the lugs.

In my point of view, the evacuation capability of the tire is the game changer out here.

Let’s see what Falken Wildpeak R/T starting with shoulder blocks and sidewall!

Loose Ground

The open shoulder blocks of Falken Wildpeak R/T are built for maximum traction. They have enough space the evacuate water, mud, or sand to keep the tread clean.

Besides that, if you look at the sequential shoulder blocks, you can see that one is in and one is out. This reduces the rolling resistance and increases the loose ground traction capability of the tire.

What I like most is these aggressive shoulder blocks are interlocked with the sidewall biters. These sidewall biters create extra biting edges under air-down conditions. Moreover, they are beefy enough to provide protection against sharp rocks on rocky terrains.

Overall, I think Falken Wildpeak R/T is a great tire for loose ground.

Rocky Terrains

Rock terrains can be divided into two. While the most important one is gravel performance for rugged terrain tires, the rock crawling performance is also important for severe off-road lovers.

First of all, Falken Wildpeak R/T has a phenomenal design that can throw small rocks out to the tread. Thanks to its stone ejector and siping angles of the center blocks. I’m not saying that it’s not going to hold any rock but I’m saying that it’s going to throw them out in a minute because wavy sipe design.

Well, it may slightly stay short regarding rock crawling because its rim protector is too small and it makes the bead open to any external damage while rock crawling. Well, I understand this because even without a bead protector, Falken Wildpeak R/T is a heavy enough tire.

A Tip: People online mostly say that Falken Wildpeak R/T is the best tire when it comes to cleaning tread. Especially on throwing stones out.

Overall, Falken Wildpeak R/T is a great tire for gravel. It also provides great grip on the rock because of its relatively wider tread section. I still don’t recommend this tire for a long-use rock crawling application because of the bead fatigue concerns.

Tire Size Selection: The Basics You Can’t Skip

P-Metric vs. LT (Light Truck) Tires

Understanding Tire Load Range: XL vs. E-Load

Then comes the tire load index and load range — essentially your tire’s strength rating. Here’s where things split between passenger XL and LT E:

XL (Extra Load) is a passenger tire with reinforced sidewalls. It can handle a bit more pressure (~41 PSI) than a standard SL tire and is perfect for SUVs, crossovers, or light trucks that carry extra gear, passengers, or small trailers. XL tires ride softer and quieter than LT options, making them ideal for daily use.
E Load Range is an LT tire class built with a much thicker casing. E-rated tires can handle far more pressure (up to ~80 PSI) and heavier loads, which makes them essential for ¾-ton and 1-ton trucks towing trailers or hauling close to max capacity. The trade-off is weight, stiffer ride, more road noise, and a small drop in fuel efficiency.

Put simply: XL is for “extra luggage and family,” while E is for “truck bed full of bricks or a car trailer.”

Why the Tire Speed Rating Matters for Safety

Conclusion

It doesn’t matter if you’re working, crawling, or towing, Falken Wildpeak R/T is a great tire because of its spec versatility. Since it’s a big and heavy tire, it sometimes shows high force numbers. However, Falken always honors its warranty if you make a purchase from validated dealers.

BF Goodrich All-Terrain T/A KO3 Review

Updated: November 11, 2025 by Emrecan Gurkan 6 Comments

Real test data, off-road insights, and daily-driving impact — from a former Bridgestone engineer.

The BFGoodrich All-Terrain T/A KO3 is the long-awaited successor to the legendary KO2 — and expectations couldn’t be higher. Classified as an Off-Road A/T tire, it builds on KO2’s legacy of sidewall toughness and off-road bite while addressing some of its shortcomings like wet braking and highway hum. If you want to see exactly how the two compare, check out our BFGoodrich KO3 vs KO2 breakdown.

With competitors like the Toyo Open Country AT3 and Falken Wildpeak AT3W(now new Wildpeak AT4W) setting new standards, BFG clearly borrowed cues in its updated tread design and compound. From our testing and driver reports, the KO3 retains the rugged durability KO-series owners demand, while adding better wet grip, refined road manners, and a modern compound that locks in its 3PMSF winter rating. It’s a tire built for trucks, Jeeps, and SUVs that need year-round dependability with true off-road capability.

In the sections ahead, we’ll break down how the KO3 performs across dry, wet, snow, and off-road testing. You can also use our All-Terrain Tire Decision Tool to instantly compare it against other A/T options for your exact vehicle.

Quick Look

BFGoodrich All-Terrain T/A KO3

Tested Rating: 8.5/10

The BFGoodrich KO3 is one of the toughest all-terrains on the market, built for durability and trail confidence. On-road, it feels steady but heavy (140-ft dry stop, 0.72 g cornering), and it asks for extra margin in the wet (184 ft, 0.46 g). In snow, it claws confidently through loose drifts (72-ft stop, 46.4-ft launch) but slides longer on packed surfaces, while on ice it stays predictable though not short-stopping (46.2 ft). Off-road is where it truly dominates, scoring 9.5 dirt, 9.5 sand, 9.2 mud, and 9.5 rock, with reinforced 3-ply sidewalls and a blocky tread that make it a goat in rocky and muddy terrain. Comfort is firm but acceptable (7.5/10), with noise building as miles stack up, while tread life runs 45–55k miles if rotations are strict.

👉 Bottom line: the KO3 is built for ¾-ton and HD trucks in rocky, dry, and off-pavement regions — less convincing in rain or snow-belt states, but unmatched in sheer toughness.

BFG KO2 vs KO3: What Changed?

In the intricate world of tire manufacturing, continuity often prevails. If a design proves successful, why reinvent the wheel, right? However, once in a while, a trailblazer like BF Goodrich disrupts the status quo.

Consider this: From the initial idea to a tire’s arrival on store shelves, a staggering three-year period typically passes. It’s quite astounding, isn’t it? You might wonder, “What could possibly take so much time?” Well, a significant chunk of this duration is dedicated to rigorous field-testing. These tires must be prepared to face a multitude of challenges.

There’s some industry buzz that BF Goodrich’s innovative wheels began turning as early as March 2020, perhaps inspired by Toyo’s AT3. In the world of tires, competition is fierce, driving innovation and evolution.

When you put the Toyo AT3 and BF Goodrich KO3 side by side, you’ll notice some parallels. The core of the BF Goodrich KO3, its center section, resembles the Toyo AT3, setting it apart from its predecessor, the KO2.

	BF Goodrich KO3	BF Goodrich KO2
Size	LT285/70R17	LT285/70R17
Tread Depth	15/32″	15/32″
Tire Weight	56 lbs	51 lbs
Section Width	11.5″	11.5″
Tread Width	8.8″	9.4”

One notable trend? The emergence of the ‘S-shape’ lug design. It’s the talk of the town, mainly because it enhances a tire’s biting edges. Think of it as giving your tire extra “teeth” for improved grip. The BF Goodrich KO3 doesn’t just adopt this trend; it refines it. By incorporating these S-shaped lugs, the KO3 creates a more consolidated center section, resulting in a welcome reduction in road noise.

However, no story is without its twists. While the KO3 boasts a host of upgrades, it’s not without its drawbacks. When navigating loose terrains, those horizontally-oriented lugs appear to present a slight challenge. But when comparing the KO2 and KO3, the latter’s horizontal orientation offers improved traction on loose terrain, albeit with potentially faster wear. BF Goodrich’s solution? A narrower tread width on the KO3. Aesthetically inclined folks, take note!

Now, let’s talk weight. The BF Goodrich KO3 is 5 lbs heavier compared to the KO2. Since both tires have the same tread depth, the weight differance is mostly caused by the compactness of BF Goodrich KO3.

In summary, the BF Goodrich KO3 emerges as a formidable contender, showcasing superior on-road finesse and wet grip, with a slight compromise on loose terrains. Particularly for those with towing or hauling needs, the KO3 stands as a compelling choice, if you’re okay with shorter life span.

A word of caution: This assessment primarily applies to the BF Goodrich KO3 specifications available for the sizes LT285/70R17 and LT275/65R20.

Dry Performance — Stable but Not Sporty

This review draws from the dataset I’ve built — a blend of structured results, community feedback, and my own short driving impressions. On dry pavement, the KO3 posts a 140-foot stop with 0.72 g cornering grip. Those numbers don’t scream agility, but they highlight what this tire does best: stability. In my own drive, it felt more like steering a tugboat than a speedboat — slow to respond, but rock steady once on line.

Drivers echo the same. A TacomaWorld driver said it “feels heavier on the wheel,” while a Jeep Gladiator owner mentioned it “stays planted once it sets.” That’s the 3-ply sidewall and blocky tread layout at work. It minimizes squirm, which builds confidence under weight, but you sacrifice nimbleness.

SUVs & crossovers: feels overbuilt, steering muted
½-tons: delivers predictable highway stability, steady under normal load
¾-ton & HD trucks: the sweet spot, stiffness matches weight and trailers

👉 Verdict: Think tugboat, not speedboat — not quick, but unshakable once moving.

Wet Performance — Needs Extra Room

On a downpour, the KO3 makes you think ahead. It stopped in 184 feet with 0.46 g traction, which is long compared to road-focused A/Ts. When I braked hard on slick asphalt, ABS buzzed early, and while the truck stayed straight, it was like running in rain gear — you’ll stay upright, but not with much snap.

Drivers online say the same. One overlander wrote “it’s fine if you give it space,” while another added “not the tire I’d pick for storm season.” That’s what happens with its harder rubber compound. The grooves move water well, but the tread itself doesn’t have the same instant adhesion as silica-rich A/Ts.

SUVs & crossovers: not ideal for storm-heavy commutes
½-tons: needs extra braking margin in the rain
¾-ton & HD trucks: tracks straight under load, though still stretches distances

👉 Verdict: Safe if you give it margin. In rain-heavy regions, a more wet-tuned A/T will inspire more confidence.

Winter & Snow — Claws Loose, Slips Packed

Fresh snow is where the KO3 feels most comfortable. It posted a 72.3-foot stop and 46.4-foot launch, and in my own drive, it clawed forward like a snowblower plowing through drifts. But once the road turned plowed and polished, braking grew longer and traction felt more like sliding with dull ski edges — steady, but slower to bite.

Owners have the same mixed take. One TacomaWorld user said it “powers through an unplowed driveway,” while another admitted it “slides longer on polished roads.” The design makes it clear why. The deep voids and aggressive shoulders shovel well in fluff, but the limited siping and firm compound reduce effectiveness once the snow hardens.

SUVs & crossovers: fine for occasional snow, but brake earlier on pack
½-tons: capable with 4WD, though plowed surfaces feel longer
¾-ton & HD trucks: weight steadies it, but hardpack still stretches stops

👉 Verdict: Great in loose snow, less convincing on plowed roads. A solid winter trail tire, not a snow-belt commuter.

Ice — Predictable but Long

On glare ice, the KO3 comes in at a 46.2-foot stop. It doesn’t bite sharply, but it doesn’t surprise you either. Driving it felt like sliding across a frozen pond in sneakers — always moving farther than you’d like, but never catching you off guard.

Community feedback matches. Drivers say it “slides gradually, not suddenly.” That’s the stiff compound and lack of dense siping limiting micro-bite. It feels safe in predictability, but physics still demand longer stops.

SUVs & crossovers: tricky unless you drive with patience
½-tons: manageable, stability systems do the heavy lifting
¾-ton & HD trucks: steadier with mass, though still long on ice

👉 Verdict: Predictable in feel, but distance is the weak spot. If icy mornings are common, pair it with a dedicated winter tire.

Off-Road — KO3’s Playground

Off-road is where the KO3 feels at home. With 9.5 dirt, 9.5 sand, 9.2 mud, and 9.5 rock, it’s a standout in its class. On the trail, it reminded me of a mountain goat — steady on rocks, balanced in dirt, and unshaken in deep mud.

Trail reports confirm it. Jeep owners call it “unstoppable on rocky climbs,” while Tacoma drivers say it “pulls through mud where others spin.” The 3-ply sidewalls, staggered shoulders, interlocking blocks, and stone ejectors make it one of the toughest A/T designs available.

SUVs & crossovers: overkill unless trails are a big part of driving
½-tons: weekend-ready, covers dirt, mud, and rock without an M/T swap
¾-ton & HD trucks: one of the best off-road tires, stable even under heavy towing

👉 Verdict: Among the best off-road A/Ts available. If trails, mud, or rock are part of your life, KO3 is built for it.

Comfort & Noise — Firm Ride, Hum That Builds

Early on, the KO3 rides firm but civilized. With a 7.5/10 comfort score, it starts out with just a faint hum. But like a new relationship, the quirks show with time — once miles stack up and rotations slip, the noise becomes harder to ignore.

Owners phrase it the same way: “quiet for how it looks — at first.” The variable pitch tread masks sound early, but the stiff carcass transmits more texture into the cabin, and uneven wear amplifies the hum as tread depth fades.

SUVs & crossovers: feels rougher and louder than most would want
½-tons: livable hum, trade-off for trail grip
¾-ton & HD trucks: feels normal, background blends with truck noise

👉 Verdict: Starts off calm, but like most A/Ts, hum grows with age. A fair trade for toughness.

Tread Life & Longevity — Tough but Demanding

Most KO3 owners report 45–55k miles when rotations are done on time. I saw even wear in my test, and forum feedback backs it up. One Reddit driver summed it up: “lasts forever if you rotate, gets loud if you don’t.”

That’s the KO3 in a nutshell. It’s like a reliable workhorse — built to punch the clock every day, but it expects you to do your part. The hard compound and deep tread resist chipping and stretch life, but skip the rotation schedule and you’ll pay in noise and uneven wear.

SUVs & crossovers: rotate religiously to avoid uneven hum
½-tons: steady, long life for mixed highway and trail use
¾-ton & HD trucks: even wear under load, stable deep into its lifespan

👉 Verdict: Durable and long-wearing, but rotations aren’t optional — they’re non-negotiable.

Where It Fits Best

The KO3 is one of the toughest all-terrains available, designed for drivers who demand durability first and are willing to trade some wet and winter polish for brute strength. It thrives on trucks that see real work and trails.

SUVs & crossovers: too aggressive unless you live off pavement or drive gravel roads daily in places like Montana or Wyoming
½-tons: a great choice for drivers in Texas, Arizona, or Nevada, where rocky desert terrain and dry heat matter more than rain traction
¾-ton & HD trucks: the ideal partner for hauling and towing in Colorado, Utah, Alberta, or British Columbia, where sidewall stability and off-road bite matter most

👉 Bottom line: The KO3 belongs in regions where the pavement ends — deserts of the Southwest, the rocky Mountain West, or rural states with gravel backroads. If you’re in the Pacific Northwest rain or Northeast snow belt, a more wet- or snow-focused A/T may be the smarter play.

Tire Size Selection: The Basics You Can’t Skip

P-Metric vs. LT (Light Truck) Tires

Understanding Tire Load Range: XL vs. E-Load

Then comes the tire load index and load range — essentially your tire’s strength rating. Here’s where things split between passenger XL and LT E:

XL (Extra Load) is a passenger tire with reinforced sidewalls. It can handle a bit more pressure (~41 PSI) than a standard SL tire and is perfect for SUVs, crossovers, or light trucks that carry extra gear, passengers, or small trailers. XL tires ride softer and quieter than LT options, making them ideal for daily use.
E Load Range is an LT tire class built with a much thicker casing. E-rated tires can handle far more pressure (up to ~80 PSI) and heavier loads, which makes them essential for ¾-ton and 1-ton trucks towing trailers or hauling close to max capacity. The trade-off is weight, stiffer ride, more road noise, and a small drop in fuel efficiency.

Put simply: XL is for “extra luggage and family,” while E is for “truck bed full of bricks or a car trailer.”

Why the Tire Speed Rating Matters for Safety

Conclusion

The KO3 isn’t trying to be a refined daily-driver tire — it’s unapologetically tough. If your life involves gravel, ranch roads, or towing through the Rockies, this tire fits like armor. But if most of your miles are wet commutes or icy highways, other all-terrains will give you more peace of mind. For drivers prioritizing strength and trail durability above all else, the KO3 is exactly what it promises to be.

Frequently Asked Questions: BFGoodrich KO3

Is the KO3 good on-road?
Yes, but it feels heavy. Dry grip is stable (140-ft stop, 0.72 g), though steering response is slower than road-biased A/Ts.
How does the KO3 handle rain?
Wet braking is a weak point (~184 ft, 0.46 traction). It stays straight under load but needs extra stopping distance.
Is the KO3 good in snow?
Strong in loose snow (72.3-ft stop, 46.4-ft launch), but less convincing on packed or plowed surfaces.
How does the KO3 perform on ice?
It stops in ~46.2 ft. Predictable slide, but longer distances mean caution is needed in icy climates.

With its exceptional dry performance, thanks to its cavitated design and biting edges, this tire delivers satisfying traction. Responsive and stable, it maneuvers well with interconnected center blocks. The Pathfinder AT shines in cornering stability, with robust sidewalls and beefy shoulder blocks. Its softer compound and zigzag sipes enhance wet traction, while the 3PMSF rating ensures decent winter performance. While road noise may be present, its relatively low tread depth offers a comfortable ride. Designed for durability and off-road performance, it excels on rocky terrains and muddy surfaces. Exclusive to Discount Tire, the Pathfinder AT comes with warranties for added peace of mind. Embark on your next adventure confidently with the Pathfinder AT, a tire that combines traction, stability, and versatility.

Dry Performance

The dry performance of all-terrain tires is generally pretty satisfying. This is because of the nature of these tires.

All-terrain tires are cavitated and have a lot of biting edges due to increasing traction capability.

The equation is similar for Pathfinder AT also. It provides pretty well dry traction. It’s expected because this tire is marked with 3PMSF.

I know 3PMSF rates the winter performance. However, 3PMSF tires have a 30% softer compound which leads them to better gripping ability.

In summary, Pathfinder AT provides decent dry performance. I’m saying decent because dry performance isn’t only dry traction. Responsiveness and cornering stability are a huge part of it.

Let’s talk about them in another section.

Responsiveness

Responsiveness of all-terrain tires related to the tread design and compound stiffness.

To provide more precise output, I prefer the analyze responsiveness by load range.

I know most of you reading this review because you want an aggressive look and looking for a budget-friendly tire.

Here are a couple of things to know before making any purchase,

If you’re changing from the all-season tires, there is no way this tire make you happy regarding responsiveness
If you’re changing from an all-terrain tire, I kindly ask you to define your needs properly. This is a concept, medium-duty tire. It’s not going to be the same as your premium brand tire (Hello Toyo AT3 of BFG KO2 owners)

Let’s get a bit more technical.

The game changer regarding responsiveness is a center rib. If the center rib is continuous or at least interlocked, the tire provides superior and quick responsiveness. As you can see Pathfinder AT has neither. Yet, its center blocks are interconnected which leads to satisfying responsiveness. However, this makes it hard to balance it might cause slight vibration at high speed.

If you’re not an aggressive driver and have an SUV or CUV, Pathfinder AT gonna make you happy for sure.

Let’s talk about 3/4 ton or above pickup owners. If you’re pulling a trailer, I think you should stay away from this tire. Interconnected tread design mostly causes a slight drift while driving. Too much danger for me. However, if you’re not pulling a trailer, it probably put you on top of the world.

If you’re not pulling a trailer, Pathfinder AT might be a good option for you. However, this design generally causes uneven wearing. So, rotation time is key for you.

Note: Pathfinder AT has relatively low tread depth which is a great advantage for superior responsiveness.

Cornering Stability

Cornering stability is where Pathfinder AT shines.

As I’ve mentioned before, this is a medium-duty tire. You can’t do severe off-road with this tire but it has a beefy and strong sidewall to provide decent stability.

Pathfinder AT has a B-rated heat resistance for p-metric sizes. This is good for cornering stability but bad for longevity.

Its robust and beefy shoulder blocks help the tire to keep its shape and provide great cornering stability.

Pathfinder AT has a unique cornering stability.

Wet Performance

The wet performance of all-terrain tires is generally questionable because of their robust compounds. These tires face severe external effects. So, they should have cut&chipping resistance.

Pathfinder AT has a slight advantage out here. While most all-terrain tires have at least a 600 UTQG rating for p-metric sizes, this dude has 500. That basically means it has a softer compound which is great for wet traction.

Well, is it enough? Not much.

Besides the soft compound, Pathfinder AT has zigzag sipes on the shoulder blocks and lateral full-depth sipes on the center section. While zigzag one increases the wet traction and decreases the aquaplaning capability, lateral ones on the center blocks prevent heel and toe-type uneven wearing.

Overall, Pathfinder AT is an alpha plus wet performance tire that also provides unique hydroplaning resistance because of its open shoulder blocks.

Winter Performance

Winter performance of all-terrain tires is generally poor if the tire doesn’t mark with 3PMSF.

Luckily, Pathfinder AT has this labeling. The label is proof that the compound of Pathfinder AT stays sticky when the weather gets cold.

Due to its soft compound and extra biting edges, Pathfinder AT provides decent traction on light snow and bare pavement.

Though, Pathfinder AT’s tread design is shining when it comes to deep or moderate snow. Its interconnected design and staggered tread block edges increase the Pathfinder AT’s self-cleaning capability. If you keep the tread clean and have that much void area in the tread, there is no way you get poor deep snow traction.

The only concern is on the ice which I don’t recommend to ride any all-terrain tire.

Overall, Pathfinder AT is a great winter tire.

Road Noise

As the tread gets cavitated, the tires get noisier. Hence, most premium tire brand prefers interlocked tread design.

Pathfinder AT has a disadvantage out here. The tire itself has tons of void area. Moreover, its center section is way much sectional and that causes too much air movement when it’s rolling. Air movement is the main reason for the road noise.

The only advantage of Pathfinder AT is its relatively low tread depth. Yet, Pathfinder AT tends to produce road noise.

If you’re changing from a mud-terrain tire, it may make you happy. For the rest, Pathfinder AT is a slightly noisy tire.

Riding Comfort

Riding comfort is highly related to an internal structure and tread pattern.

For instance, when you use e-rated tires instead of C-rated ones, you’re going to feel bumps because the internal structure is too stiff. On the other hand, if you use SL tires instead of C-rated ones, you’re going to have way much smooth riding. This doesn’t mean you can use any tire you want. First, your tires should match the minimum load and speed requirements of your vehicle.

Let’s go back to the point. Pathfinder AT has a stiff internal structure. Its beefy sidewalls and multiple-ply sidewalls are proof of that. Yet, its relatively low tread depth is a good sign for a comfortable ride.

Overall, if you’re looking for a street tread, this isn’t your tire and it will provide a rough ride. If you need something for your working truck, please welcome a smooth ride.

Tread Life

Even though Discount Tire claims that this tire is a long-lasting one. I strongly believe that it highly depends on your use conditions and vehicle.

SUV owners,

If you’re okay with a slightly rough ride and road noise, this tire will provide decent tread life.

1/2 ton truck owners,

I think these tires are a great fit for you. Pathfinder AT is a definition of a mid-grade AT tire.

3/4 ton or above truck owners,

It might make you feel in heaven regarding traction. Though, your vehicle will eat up its fluffy compound. It’s still a great option if you don’t drive too many miles.

Getting maximum wear life from a tire is related to you as well as your tire,

Off-Road Performance

The main features of Pathfinder AT are durability and lose ground traction. As it is seen, there are great features for off-road performance.

Due to its beefy and durable sidewalls, Pathfinder AT performs pretty well on rocky terrains. However, you should keep your usage time limited because this tire heats up very quickly and that causes quick wearing.

Moreover, its voided tread is great for muddy surfaces. Besides that, its self-cleaning capability is a huge advantage.

Because of its soft compound, the tire has a unique gripping capability which is great for dirt and gravel traction.

Overall, Pathfinder AT is a great off-road tire for short-term use. So, it’s great for construction sites. Yet, I don’t recommend this tire for long-distance off-road usage or adventurous usage like rock crawling or deep mud crawling.

Warranty

Discount Tire offers different warranties depending on the size.

For P-metric tires: Discount Tire offers 55,000 miles treadwear warranty

For LT sizes: Discount Tire offers 50,000 miles treadwear warranty.

For Flotation Sizes: There is no treadwear warranty

Note: Available sizes can change from time to time. I highly recommend Discount Tire – PathFinder AT product page for a piece of certain information.

Size Selection

Before we dive into selecting the right tire size, it’s essential to understand the tire standards that manufacturers follow.

Technical Standards & Regulations

In Europe, the tire standardizing organization is called ETRTO. In the United States, it’s The Tire and Rim Association (TRA), while in Japan, it’s the Japanese Automobile Tire Manufacturers Association (JATMA). Although there may be other organizations, they generally align with one of these three.

When it comes to passenger car tires, TRA designates them by placing the letter “P” in front of the size to indicate conformity to the TRA standard. On the other hand, ETRTO and JATMA do not use any letters, which can sometimes be confusing when determining which standard is being used.

For light truck tires, TRA uses the letters “LT” in front of the tire size, while JATMA places the letters “LT” after the size. ETRTO, however, uses the letter “C” after the size to indicate tires of this type.

In the realm of medium truck tires, ETRTO uses the letter “C” after the size to designate tires designed according to their standard. In contrast, TRA and JATMA do not use any letters in this context.

Now, here’s what’s essential: Tires with the same dimensions (size) may have different maximum load capacities depending on the standard being followed. So, it’s crucial to consider the relevant standard when choosing tires.

When it comes to load capacity designations, “SL” (Standard Load) and “XL” (Extra Load) are used for all passenger car tires, regardless of which standard is being followed. In the ETRTO standard, “Reinforced” is also used as an alternative to “XL.”

Load Range, on the other hand, is specific to TRA. ETRTO and JATMA use the term “Load Index.” While TRA references Load Indexes, it’s important to note that the values provided are approximate.

To sum it up, understanding the tire standards and designations is vital as they play a significant role in determining the right tire size and load capacity. By considering the appropriate standards, you can make an informed decision when selecting tires that meet your vehicle’s requirements.

Here are two great articles if you wanna dive deeper:

Load Range vs Load Index: https://www.discounttire.com/learn/load-range-load-index

Tire Sizing System: https://www.discounttire.com/learn/euro-vs-pmetric-tires

How to Select the Right Tire Size Based on Your Requirements?

When it comes to selecting tire sizes for your vehicle, it’s important to keep in mind that most vehicles offer more than one original equipment size. Let’s take the 2019 Ford F-150 Lariat Crew Cab 4WD as an example. You have three different tire size options: 275/55R20 SL, 275/65R18 Load Range C, or 275/65R18 SL.

Note: I use Toyo Open Country AT3 for an example tire. You can use this link to see tire options for your vehicle and then make a comparison between the sizes:
https://www.discounttire.com/fitment/vehicle

If you don’t know your tire size: https://tireterrain.com/find-tires-by-vin-number/

Let’s focus on comparing the 275/65R18 SL and 275/65R18 Load Range C options for a more detailed comparison. Your decision should be based on your priorities. If you prioritize a smooth ride and better handling, the SL option is the way to go. On the other hand, if you value hauling or towing performance and tire longevity, the Load Range C option would be a better fit.

As a tire engineer, my perspective often revolves around load-carrying capacity. Generally, tires with higher load capabilities tend to provide a stiffer ride. However, there’s a bit of an illusion to consider. When you compare the two tires in the same size, the SL-rated tire may initially appear to have a higher load capability. But here’s the catch: P metric tires, like the SL option, need to be derated by a factor of 1.1 when used on a truck. Crunching the numbers reveals that the SL option actually has a lower maximum load capability. Additionally, it boasts a lower tread depth, which translates to better responsiveness.

The same principles I mentioned earlier also apply when comparing XL and E Load range tires. In summary, if your vehicle allows for Passenger Car or LT (Light Truck) tires, going with a passenger option will provide you with better on-road manners. However, if you find yourself venturing off-road frequently, own a working truck, or regularly engage in towing and hauling heavy loads, then LT tires are generally the better choice for your needs.

Couple of tips for towing;

Even though the load index of passenger car tires fits, when it comes to towing, sidewall stability is the issue. Hence, LT tires with Load Range C, D, or E provide better stability.
Generally, a load index higher than 119 is recommended for towing
Proper loading is important for even wearing. 60/40 rule should be followed. 60% of the weight should be on the front axle and 40%of weight should be applied rear axle of the trailer. Besides that, try to center load. Start with heavier ones if you gonna stack them up.

To wrap it up, selecting the right tires comes down to choosing the ones that align with your driving preferences and specific requirements.

Conclusion

Pathfinder AT is a mid-grade tire that can be described as a “Jack of all trades, master of none.” From my perspective, it performs well as a tire suitable for both off-road (50%) and highway (50%) driving. However, it may not excel in terms of reducing road noise and providing optimal comfort. On the other hand, it offers excellent durability. Whether it becomes your best or worst tire depends on your specific expectations. I have provided a summarized overview in the table below, tailored to different types of vehicles.

Cooper Discoverer AT3 4S Review — Quiet Comfort & Winter Performance Tested in 2025

Updated: September 30, 2025 by Emrecan Gurkan Leave a Comment

Real test data, off-road insights, and daily-driving impact — from a former Bridgestone engineer.

The Cooper Discoverer AT3 4S is a comfort-driven On-Road A/T tire built for SUVs, CUVs, and light-duty pickups. Unlike tougher Off-Road A/Ts, it’s tuned for highway manners first — offering a smooth ride, dependable wet and winter traction, and a stylish design that appeals to drivers who want all-terrain looks without the harshness of a rugged tire.

From our testing and driver feedback, the AT3 4S is a great match for mall crawlers, full-size SUV owners, and casual off-roaders who stick to dirt trails or gravel roads rather than mud and rocks. Its main trade-off is limited bite in severe terrain, but for most daily drivers, it delivers a strong balance of comfort, control, and light-duty capability.

In the sections ahead, we’ll break down how the AT3 4S performs across dry, wet, winter, and light off-road testing — and if you want to see how it stacks up against other options for your exact vehicle, our All-Terrain Tire Decision Tool makes it easy.

From my standpoint as a former Bridgestone engineer, the Cooper Discoverer AT3 4S is a reliable on-road tire that delivers excellent handling and true 4-season traction. Its soft compound gives it strong grip, but also means it doesn’t deliver long tread life on heavy pickups (5,000+ lbs). With its mild tread pattern, it provides a quiet, almost muted ride, though this same feature limits its rocky terrain performance. On gravel and rock, it tends to wear quickly, making it less suitable for extended use in those conditions. That said, its strong sidewalls hold up well and make it a dependable option for occasional off-road driving without worry.

Dry Traction

If I’m writing about all-terrain tires, I generally start my analysis with dry traction.

The reason is simple. These tires are made for traction and dry traction is the easiest one you can get.

Unlike wet and dry traction, more rubber on the ground means better dry traction.

Cooper Discoverer AT3 4S is a compact tire that has relatively less void area than its competitors. That basically means this tire can put more rubber on the ground. Moreover, the tire is built for winter. For this reason, it has a fluffy compound and notched tread that offers excellent traction capability.

Cooper Discoverer AT3 4S provides unique dry traction. Yet, I still recommend considering below points out;

This is a nimble tire, it’s a good option for quick starting
Since it has a soft design, its rolling resistance is low and which means better acceleration
I like the stopping distance on dry, we’ll talk about wet later

Steering Response

Steering response is an issue for all-terrain tires.

The slow steering response is natural for all-terrain tires because of their heavy structure and cavitied tread. So, if you’re not familiar to use this tire category, you’ll probably swear never to buy all-terrain tires again. Even Cooper Discover AT3 4S.

I said even Discoverer AT3 4S because, in my point of view, this tire offers one of the best handling in its category.

The steering response is mostly related to the weight of the tire and the center section design.

First of all, Cooper Discoverer AT3 4S doesn’t have an interlocked center section which is bad for traction but great for responsiveness.

In that case, a rib-type design works best. Even though Cooper Discoverer AT3 4S doesn’t have a full rib type design, its design is similar to all-weather tires. I like to call this design ‘hybrid’.

Due to its half lug – half rib design and relatively continuous center rib (compared to other all-terrain tires, this is way much more continuous) Cooper Discover AT3 4S offers alpha plus steering response.

Note: Cooper Discover AT3 has a similar weight to its competitors. While I’m making this comparison, I only put P-rated tires into consideration.

Cornering Stability

Cornering stability sometimes can be an issue for all-terrain tires.

All-terrain tires can be used on CUVs, SUVs, and pickup trucks. In fact, this is the reason some of them have poor cornering stability on heavy vehicles.

Cornering stability is related to strong sidewalls and inner structure. So, here is the deal.

If you make the sidewall and inner structure too stiff, due to aggressive tread, you notice bumps/cracks/uneven pavement pretty strong.

Because of the above reasons, manufacturers start to classify all-terrain tires.

For instance,

Cooper Discoverer AT3 4S – SUV, CUV, 1/2 ton trucks
Cooper Discoverer AT3 XLT – Hauling, towing, above 1/2 ton trucks

Cooper Discoverer AT3 4S’s inner structure contains an extra nylon reinforcement that helps the tire to keep its shape at high velocity. Besides that, this tire has a B-rated heat resistance which means it has thick sidewalls.

Due to its robust shoulder blocks and inner structure, Cooper Discoverer AT3 4S offers exceptional cornering stability. It may even give you a rough ride for a while. I’m gonna talk about it in the next section.

Ride Comfort

Since all-terrain tires should work air-down conditions also, these tires have a robust but flexible inner structure which generally provides decent ride comfort.

Riding comfort is mostly related to the inner structure. I’ve already talked about it. So, I’m gonna keep it short.

First of all, Cooper Discoverer AT3 4S is only available in p-metric sizes which makes it a kinda comfort driven tire.

Secondly, this tire has a soft and compact design. This is great for a smooth ride. Especially if you combine this with a fluffy compound like Cooper did.

As a result of the above items, Cooper Discoverer AT3 4S offers a smooth ride. Though worth reminding, when this tire is new, you may feel a bit bumpy. Especially if you have CUV or a relatively smaller SUV. No worries, this is totally expected. That happens on the tires with strong beads.

Road Noise

All-terrain tires tend to make noise because of their voided patterns.

In that case, if you decrease the void area on the center section, you can get a deaf tire. However, it isn’t always possible for all-terrain tires.

Most manufacturers use the interlocked center section due to decrease void areas.

Since Cooper Discoverer AT3 4S is somewhere between highway terrain and all-terrain tire, it has a rib-like type pattern that decreases the center section void area.

The disadvantage of this kind of pattern is if you want decent loose-ground traction, you should make an aggressive shoulder design.

That’s what Cooper did on Discoverer AT3 4S. This tire has differently sized and robust shoulder blocks. When you make differently-sized shoulder blocks, you should give them some space the work better. Like Toyo Open Country AT3, Cooper Discoverer AT3 4S have a wide space between two shoulder blocks.

Because of the above reasons, you can find Cooper Discoverer AT3 4S a bit noisy if you’re changing from all-season tires. For others, this tire is quite as a church mouse compare to its competitors.

Wet Performance

The wet performance of all-terrain tires sometimes can be tricky.

Even though these tires are made for traction and have tons of biting edges (edges of lugs, shoulder blocks, etc.), they sometimes fail on wet traction.

So, why do these tires spin on wet surfaces?

Because these tires have stiff and generally cut & chipped resistant compounds that have a huge issue on the wet grip.

In order to avoid this manufacturers should use sipes and notches that increase the number of biting edges and provide a decent wet grip. However, this also causes an increase in rolling resistance and decrease your MPG.

Besides the wet traction, hydroplaning resistance is also a huge game-changer in the wet performance. Luckily, all-terrain tires have an advantage out here, well at least not flotation-size ones.

Now that we have the necessary information, let’s talk a little bit about Cooper Discoverer AT3 4S. I’m going into particulars at bottom booms.

Wet Traction

As I’ve mentioned before, wet traction is related to sipe density and compound stiffness.

In that case, the easiest way to understand the compound and sipe density combinations is by checking the UTQG rating.

Cooper Discoverer AT3 4S’s UTQG rating is 620 A B for all sizes. That basically means this tire has A-rated wet traction and B-rated heat resistance and the number means it lasts 6.2 times more than the test tire ( doesn’t mean anything for longevity).

These metrics are great for decent wet traction. Besides that, the micro-gauge sipes on the blocks are creating tons of biting edges and provide excellent wet traction. The only problem is these sipes are increasing fuel consumption. In fact, that was the reason Cooper changed the sipe density of the Cooper Discoverer AT3 and released three different versions of this tire.

Cooper Discoverer AT3 4S has more sides than Cooper Discoverer AT3 and has bigger lugs. This is actually a huge sign of the building intent of this tire. This tire is more pavement-driven. Hence, its loose-ground performance isn’t satisfying as the old Cooper Discoverer AT3. Yet, this is a huge update for wet and light snow traction.

The only issue is the extra sipes aren’t full-depth. That actually means that this tire has different compound layers. Not an issue for wet traction but regarding longevity it’s an issue. I’ll talk about it later on.

Due to its sipe density and relatively soft compound, Cooper Discoverer AT3 4S provides excellent wet traction. One of the best in its segment.

Hydroplaning Resistance

Hydroplaning resistance is basically the water evacuation capability of the tires. In that case, circumferential grooves and shoulder slots do most of the job.

Since all-terrain tires should provide loose ground traction, these tires have a sufficient amount of void area for reliable hydroplaning resistance.

The issue out here is the size of all-terrain tires. Wider tires always tend to hydroplane more. For this reason, mud tires are flotation-size tires that sometimes cause this issue.

Luckily, Cooper Discoverer AT3 4S has a 5-rib design that contains 4 circumferential grooves. Cooper calls them Aqua Vac Channels. Besides that, its open shoulder blocks evacuate the water with ease.

Moreover, this tire is only available in p-metric sizes. Hence, hydroplaning isn’t an issue for this tire.

Cooper Discoverer AT3 4S provides trustworthy hydroplaning resistance.

Winter Performance

Winter performance of all-terrain tires is inconsistent because of their stiff compounds.

In fact, the tread design and sipe density are generally good enough to provide decent winter performance.

However, due to the stiff compound, not all winter conditions are suitable for these tires.

For this reason, I prefer to divide this section into three by weather conditions.

Light Snow Traction

Light snow traction is similar to wet traction because this condition doesn’t require a self-cleaning capability.

The first thing you have to pay attention to out here is the 3PMSF label.

This label means that Cooper Discoverer AT3 4S’s compound doesn’t lose traction capability under 7 Celcius degrees.

If the tire doesn’t have this label, the compound gets stiffer in cold weather and it causes a decrease in the grip capability.

Due to its winter-specified compound and sipe density, Cooper Discoverer AT3 4S provides decent light snow traction. I’m not going to say it’s excellent because I strongly believe that halfway through sipes isn’t gonna work for a long time.

Deep Snow Traction

Deep snow traction is part of loose ground traction. For this reason, the void area ratio is highly important.

Cooper Discoverer AT3 4S is a great deep snow tire because it has a deep tread, soft compound, independent lug design, and most importantly sawtooth snow grooves that increase the snow grip significantly.

Ice Traction

Even though Cooper Discoverer AT3 4S has a 3PMSF marking, it isn’t a dedicated winter tire. For this reason, trusting this tire on the ice is a bit utopic for me.

Actually, its tread design is perfect for ice traction. But I keep coming back to sipes and compound stiffness.

Even though this tire has a relatively soft compound compared to its competitors, it’s still way behind for a decent ice performance.

Luckily, Cooper Discoverer AT3 4S is a narrow tire because it’s only available in p-metric sizes. Narrow tires work better on snow and slush.

I can’t say it provides trustworthy ice performance, yet, it can take you out of unexpected situations.

Treadwear

I know most of you wonder why people have different ideas about the tread life of this tire.

I’m going to say to same things I said before, I don’t like the promoting way of the manufacturers.

First of all, even though Cooper Discoverer AT3 4S is an all-terrain tire that mostly focuses on on-road driving. For this reason, its compound is fluffy and its design is soft.

Besides everything I said, because of the halfway-through sipes, this tire has two different compound layers. As you can guess, the second layer is fluffier.

I strongly believe that you should know what to expect from this tire regarding longevity. I recommend putting the below items into consideration.

This isn’t a tire for hauling or towing
If you gonna use this tire mostly on gravel, there is no way that you get a decent tread life
Since this tire has B-rated heat resistance, I don’t recommend this tire for over 5,000 lb vehicles

Cooper Discoverer AT3 4S can provide a decent life for trucks if you mostly drive on the streets.

Cooper Discoverer AT3 4S can provide a decent tread life for SUVs and CUVs.

Getting maximum wear life from a tire is related to you as well as your tire,

If you’d like to learn how to get maximum tread life:

Warranty

Cooper offers 65,000 miles and 6 years treadwear warranty for this product
They also offer 45 days road test guarantee (meanless to me, different compound layers perform differently)
Free to exchange for other Cooper brand tires (most of you will need an LT tire, so go with Cooper Discoverer AT3 XLT in that case)

If you need a piece of additional information;

Off-Road Performance

When I first time this tire, I was pretty sure that the intent of this tire isn’t off-road.

Cooper Discoverer AT3 4S has a mild design that doesn’t have enough void area for relatively severe off-road conditions.

If you need a tire for hunting, rock crawling or etc, this isn’t your tire.

On the other hand, if you do only drive off-road occasionally, this’s a great tire for you.

The good thing is Cooper Discoverer AT3 4S has strong sidewalls and bead construction. For this reason, it isn’t vulnerable to outside effects. In my point of view, this is way much more important for a mostly city driving tire.

From now on, I’m going to evaluate the performance of Cooper Discoverer AT3 4S for different off-road conditions.

Gravel

Gravel and dirt traction are what most of you want. Well, Cooper knows that and that’s why they’re actually limiting the off-road performance of this tire.

Regarding gravel, the sipe density and the fluffy compound work perfectly. Well, at least if we are talking about only traction.

Besides that, Cooper Discoverer AT3 4S has differently sized shoulder lugs that increase the rocky terrain traction significantly.

However, because of the fluffy compound and the too many sipes, Cooper Discoverer AT3 4S will wear fast at the beginning of its tread life.

Cooper Discoverer AT3 4S is great for occasional gravel, yet, if you have to drive on gravel for a while, especially if you’re living in a warm region, it can’t provide you decent tread life.

Dirt

Dirt traction is the easiest one the reach. It is mostly related to the number of biting edges. For this reason, even the worst all-terrain tire provides decent dirt traction.

Cooper Discoverer AT3 4S actually has an advantage out here. This tire has a fluffy compound. For this reason, it’s stickier than its competitors.

Dirt isn’t abrasive. Hence, driving on the dirt will not decrease the tread life of Cooper Discoverer AT3 4S.

Cooper Discoverer AT3 4S is an excellent option for dirt driving. Besides the traction, due to the amount of rubber on the ground, it provides way much better handling than its competitors.

Sand

Sand driving is where this tire shines.

Unlike most people think, the best tire on the sand is the mildest one.

The aggressive design tires dig too deep and cause a stuck. In fact, that’s the reason that all-terrain or mud-terrain tires are more expansive than passenger tires.

In that case, the most crucial thing is self-cleaning capability. Even though the independent lugs sometimes cause a lack of self-cleaning, Cooper Discoverer AT3 4S’s staggered groove walls do this job.

Cooper Discoverer AT4 4S is an excellent tire for sand driving. I strongly recommend it.

Mud

Even though this kind of tire isn’t suitable for mud adventure, they’re okay for occasional mud.

In that case, the essential thing is self-cleaning capability.

The issue with Cooper Discoverer AT3 4S is its self-cleaning capability isn’t good enough for deep mud. Relatively deeper of a long distance mud conditions fill the tread with mud and because of the narrow shoulder slots, evacuating this mud is almost impossible.

If you face mud often, I don’t recommend Cooper Discoverer AT3 4S, however, it’s great for half muddy – half smooth road conditions.

Tire Size Selection: The Basics You Can’t Skip

P-Metric vs. LT (Light Truck) Tires

Understanding Tire Load Range: XL vs. E-Load

Then comes the tire load index and load range — essentially your tire’s strength rating. Here’s where things split between passenger XL and LT E:

XL (Extra Load) is a passenger tire with reinforced sidewalls. It can handle a bit more pressure (~41 PSI) than a standard SL tire and is perfect for SUVs, crossovers, or light trucks that carry extra gear, passengers, or small trailers. XL tires ride softer and quieter than LT options, making them ideal for daily use.
E Load Range is an LT tire class built with a much thicker casing. E-rated tires can handle far more pressure (up to ~80 PSI) and heavier loads, which makes them essential for ¾-ton and 1-ton trucks towing trailers or hauling close to max capacity. The trade-off is weight, stiffer ride, more road noise, and a small drop in fuel efficiency.

Put simply: XL is for “extra luggage and family,” while E is for “truck bed full of bricks or a car trailer.”

Why the Tire Speed Rating Matters for Safety

Conclusion

Cooper Discoverer AT3 4S is a comfort-driven all-terrain tire that provides great handling, reliable winter traction, and trustworthy mild off-road traction. It’s a good option for its price. Yet, you better put the below points into consideration before making any purchase.

	Cooper Discoverer AT3 4S
