Cooper Discoverer AT3 4S is an on-road all-terrain tire mainly developed for SUVs, CUVs, and pickup trucks. Since Cooper Discoverer AT3 4S is a comfort-driven and handsome tire, it’s a good option for mall crawlers, rookie off-roaders, and especially for full-size SUV owners who isn’t the casual off-road driver but love being on the dirt when they have time. In this article, I’m going to expose Cooper Discoverer AT3 4S. Let’s see if it’s a good option for you!

As a former Bridgestone engineer, from my standpoint, Cooper Discoverer AT3 4S is a reliable on-road tire that offers excellent handling and 4-season traction. Since it has a soft compound, it doesn’t provide decent tread life for over 5,000 lb pickups. Cooper Discoverer AT3 4S has a mild tread pattern that provides a deaf ride. However, this feature limits its rocky terrain performance. Moreover, it wears quickly on gravel and rock. For this reason, it’s not suitable for an extended period of time for gravel and rock usage. On the other hand, Cooper Discoverer AT3 4S has strong sidewalls that work perfectly on the occasional off-road conditions.

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;
Cooper Discoverer AT3 4S Warranty Document:
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.
