For years, both the Yokohama Geolandar AT4 and Toyo Open Country AT3 have been popular choices across the US and Canada. Since testing both tires extensively, one thing has become clear: these tires serve fundamentally different purposes. The Yokohama Geolandar AT4 is built as an on-road AT tire focused on daily comfort and highway manners. The Toyo Open Country AT3, by contrast, has evolved into a genuine off-road AT tire with significantly improved wet performance and trail capability. As a former Bridgestone engineer, I’ve tracked how both tires have developed, and the gap between them has widened considerably. In this definitive comparison, I’ll dive into the test data, synthesize customer feedback, and offer my personal observations on which tire makes sense for your truck or SUV. Let’s roll.
Quick Look
Toyo Open Country A/T III

Yokohama Geolandar A/T4

Toyo Open Country AT3 is built for off-road capability with serious wet performance. Its reinforced shoulders and staggered tread blocks resist flex, delivering sharp handling and 0.72g cornering grip. Stopping at 164 feet in wet conditions with 0.57g traction, it’s significantly improved over previous generations. Off-road scores of 8.8 dirt, 8.7 sand, 8.2 mud, and 8.2 rock show genuine trail competence, with owners consistently praising its snow traction and trail composure. The stiff casing delivers excellent durability and responsive feedback. Comfort sits at 6.0, reflecting the firmer construction and road hum. Yokohama Geolandar AT4 takes the opposite approach as an on-road AT focused on highway use, but it underdelivers. Despite its reputation for smooth predictability on long highway runs, wet performance lags at 177 feet with 0.52g traction, a 13-foot gap behind the Toyo. Off-road capability averages 7.35, suitable for light trails but clearly pavement-focused. Comfort is 5.75, actually lower than the Toyo despite the marketing emphasis on quiet manners. The Yokohama’s only real advantages are slightly better winter stopping at 71.85 feet and less aggressive dry braking at 141 feet. For most buyers, the Toyo offers better all-around performance.
Raw Test Data
Dry Performance: Toyo Takes the Edge
On pavement, Toyo stops in 134 feet with 0.72g cornering, while Yokohama needs 141 feet with 0.70g. That 7-foot gap and slight cornering advantage show Toyo is more responsive and planted. The Toyo feels sharper and more road-tire-like in feedback, while Yokohama takes longer to settle but cruises smoothly once stable.
Drivers echo the split. Toyo owners note it “takes feedback quickly” and feels confident through corners, while Geolandar drivers say it “stays composed and calm, never twitchy.” From my testing, Toyo’s reinforced shoulders and staggered tread blocks resist flex under cornering load, giving it that sharper edge. Yokohama’s softer compound and rib-focused design lean toward a calmer, less aggressive feel, prioritizing smooth highway cruising over sharp handling.
For different trucks:
- SUVs & crossovers: Yokohama feels smoother for daily commuting, but Toyo is more engaging.
- ½-ton trucks: Toyo gives sharper response; Yokohama better for long highway stretches.
- ¾-ton & HD trucks: Toyo stays steadier when loaded; Yokohama feels less locked-in with weight.
👉 Verdict: Toyo delivers sharper dry response and better cornering grip. Yokohama steadies out at highway speed but lacks bite when you need it.
In the rain, the gap is clear and significant. Toyo stops in 164 feet with 0.57g traction, while Yokohama needs 177 feet with just 0.52g. That’s a 13-foot advantage for the Toyo, a meaningful difference when conditions turn bad. Toyo also delivers stronger wet traction across the board, making it the safer choice in heavy rain.
This is a complete reversal from the previous generation. Community feedback reflects the improvement: Toyo owners now report “confident in the rain, even loaded” and “grips well on slick pavement.” Yokohama drivers, by contrast, note it’s “adequate but not aggressive” in wet conditions. The explanation lies in Toyo’s compound improvement. The new formulation balances durability with wet grip, while Yokohama’s harder compound prioritizes tread life over wet adhesion.
For different trucks:
- SUVs & crossovers: Toyo is the safer choice in rainy climates.
- ½-ton trucks: Toyo delivers better wet stopping and traction.
- ¾-ton & HD trucks: Toyo stays more predictable under weight when roads are slick.
👉 Verdict: Toyo wins wet performance decisively. The 13-foot stopping gap and stronger traction make it the clear choice for rain-prone regions. Yokohama falls short where on-road ATs should excel.
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: Toyo Launches Better, Yokohama Stops Slightly Shorter
In snow, Yokohama stops at 71.85 feet and launches in 47.79 feet, compared to Toyo’s 75.1 feet stop and 42.7 feet launch. That means Yokohama brakes about 3 feet shorter, but Toyo pulls away 5 feet quicker. In real use, Toyo feels more confident in deeper, unpacked snow thanks to its staggered shoulders and aggressive tread, while Yokohama is calmer on salted and plowed lanes.
Driver feedback reflects the difference. Toyo owners call it “confident in winter, bites well in fresh snow,” while Geolandar users note it’s “safe and easy in winter, but not aggressive.” The design explains it: Toyo has dense siping and compound tuning to stay pliable in cold, while Yokohama keeps rubber firmer, trading deep-snow bite for stability on cleared roads.
For different trucks:
- SUVs & crossovers: Yokohama feels steadier on plowed commutes; Toyo better when snow piles up.
- ½-ton trucks: Toyo wins when fresh snow covers roads.
- ¾-ton & HD trucks: Toyo stronger under weight; Yokohama too muted for heavy snow use.
👉 Verdict: Toyo is the better deep-snow performer with quicker launches. Yokohama’s only advantage is slightly shorter stopping on packed snow.
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.
Ice Performance: Toyo Edges Ahead, Both Have Limits
Ice is where both tires show their limits. Toyo stops in 46.5 feet, while Yokohama stretches to 48.5 feet. That 2-foot gap is noticeable when you’re sliding on glassy surfaces. Toyo slides but gives you time to correct with progressive grip fade, while Yokohama feels like it fades away more suddenly.
Drivers say it clearly: Toyo users admit it’s “fine if you’re careful, but not a studded alternative.” Yokohama owners echo: “not scary, but not a true ice tire.” The tech shows why: Toyo’s micro-siping and pliable compound keep a touch of grip, while Yokohama’s harder compound limits edge effect on glassy ice.
For different trucks:
- SUVs & crossovers: Both demand caution; Toyo is a bit safer.
- ½-ton trucks: Toyo gives better recovery time on ice.
- ¾-ton & HD trucks: Neither is ideal, but Toyo steadier under load.
👉 Verdict: Toyo edges ahead with shorter stopping and more predictable grip fade, but neither tire is a go-to ice solution. If you face ice regularly, dedicated winter tires are the answer.
Off-Road Performance: Toyo Dominates by a Wide Margin

Off-road scores make the split undeniable. Toyo posts 8.8 dirt / 8.7 sand / 8.2 mud / 8.2 rock, while Yokohama trails at 7.7 dirt / 7.4 sand / 7.1 mud / 7.2 rock. That’s more than a 1-point gap across every surface. Toyo is a genuine off-road tire that can tackle mixed trails confidently, while Yokohama is suitable for gravel roads and light dirt but clearly not built for serious trail use.
Owners confirm it. Toyo users mention it “grabs in ruts and feels planted on loose terrain.” Geolandar drivers frame it differently: “fine on gravel, not for rock crawling, and that’s okay.” From an engineering perspective, Toyo’s reinforced casing and staggered tread blocks keep edges stiff under torque, while Yokohama’s lighter rib design reduces harshness on pavement but gives up trail aggression.
For different trucks:
- SUVs & crossovers: Yokohama for highway comfort; Toyo for trail weekends.
- ½-ton trucks: Toyo is the solid choice for real off-road capability.
- ¾-ton & HD trucks: Toyo holds together on rocks and mud; Yokohama underbuilt for punishment.
👉 Verdict: Toyo dominates off-road with over 1 point higher on every surface. Yokohama is strictly for pavement and light gravel. If you actually use trails, this isn’t even close.
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.
Here’s where the data surprises. Toyo scores 6.0 comfort, compared to Yokohama’s 5.75. Despite being marketed as the highway-focused tire, Yokohama is actually noisier and less comfortable than the Toyo. Both are on the louder end for AT tires (max in class is 7.33), but Toyo edges ahead.
The difference is noticeable on long highway runs. Toyo has a firmer ride with road hum, especially on uneven pavement, but it’s not harsh. Yokohama is also noisy, and drivers note it doesn’t deliver the quiet comfort you’d expect from an on-road AT. Forum voices reflect the disappointment: Geolandar owners mention “more road noise than expected for a highway tire,” while Toyo owners acknowledge the “hum from the stiff casing but nothing annoying.”
The explanation: Toyo’s reinforced construction transmits more feedback but stays planted. Yokohama’s design doesn’t effectively dampen noise despite the on-road focus.
For different trucks:
- SUVs & crossovers: Both are acceptably noisy; Toyo slightly better.
- ½-ton trucks: Toyo wins on comfort despite being the off-road tire.
- ¾-ton & HD trucks: Noise blends into road noise anyway; Toyo firmer but more stable.
👉 Verdict: Toyo is slightly more comfortable at 6.0 vs 5.75. Ironically, the off-road tire beats the on-road tire on highway comfort. Both are loud for the AT category.
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.
Who Should Buy Which Tire: Clear Choices Based on Real Use
Yokohama Geolandar A/T4: Best fit for buyers who prioritize slightly better winter stopping on packed snow and don’t venture off pavement. It’s acceptable for daily commuting in areas with plowed winter roads, but it underdelivers on wet performance, comfort, and off-road capability compared to what you’d expect from an on-road AT. Honestly, unless winter stopping on packed snow is your top priority, there are better options in this category.
Toyo Open Country A/T III: Suited for drivers who need genuine off-road capability, excellent wet performance, and versatile all-around use. Stronger in wet conditions (13-foot advantage), significantly better off-road (1+ point higher on every surface), superior on ice, and surprisingly more comfortable despite being the off-road-focused tire. Ideal for mountain states, anyone who actually uses trails, and trucks that see varied conditions. Works for SUVs, ½-ton, and ¾-ton trucks equally well.
👉 Bottom line: The data tells a clear story. Toyo wins decisively in wet, off-road, ice, dry, and even comfort. Yokohama’s only advantage is 3 feet shorter stopping on packed snow. For most buyers, the Toyo is the better tire unless you specifically need that one winter metric and never drive in rain or off-road.
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.
Who Should Buy Which Tire: The Data Tells a Clear Story
If you value better wet performance, stronger off-road capability, superior ice stopping, and surprisingly better comfort, the Toyo Open Country AT3 is the clear choice. It stops 13 feet shorter in the wet, scores over 1 point higher on every off-road surface, handles ice better at 46.5 feet versus 48.5 feet, and even rates higher on comfort (6.0 vs 5.75). It’s ideal for anyone who drives in rain, uses trails regularly, faces winter conditions, or needs a genuinely versatile tire.
If you specifically need slightly better stopping on packed snow (71.85 ft vs 75.1 ft) and never drive in rain, off-road, or on ice, the Yokohama Geolandar A/T4 could work. But honestly, that’s a very narrow use case. The Yokohama underdelivers as an on-road AT by losing on wet performance and comfort, the two things it should excel at.
For different buyers:
- Rain-prone regions (Southeast, Pacific Northwest): Toyo wins decisively with 13-foot wet advantage
- Snow-belt states: Toyo better on ice and snow acceleration; Yokohama only edges on packed snow stopping
- Off-road use (even occasionally): Toyo is the only real option
- Pure highway commuting with plowed winter roads: Yokohama’s only viable scenario
👉 Bottom line: The Toyo is the better tire for most buyers. It beats the Yokohama in wet, off-road, ice, dry handling, and comfort. Yokohama’s single advantage (3 feet on packed snow stopping) doesn’t justify its weaknesses everywhere else.
