Cooper Discoverer AT3 XLT vs Goodyear Wrangler TrailRunner AT

An average tire would last you four to five years easily and if you’re not the off-roading type, and do most of your driving on highways, a good tire could even last up to seven years. However, for the off-roaders out there, picking the right tire can make all the difference when driving on difficult trains.

Why an all-terrain tire?

What makes all-terrain tires different from your normal everyday tires is that they are just as dependable off-road as they are on the highway. They provide you grip and traction on all sorts of different terrains whether it’s gravel, snow, mud, or rain.

So, if you’re looking for the right all-terrain tires for your vehicle you need to know that two of the best tires in the market right now are the Goodyear Wrangler Trailrunner AT and Cooper AT3. However, both of these are equally as good which makes it tough to pick one.

An in-depth look into the specs of both these tires will give you a better idea as to which one will work the best for you.

About Goodyear Wrangler trailrunner

The Goodyear trailrunner is quite similar to Goodyear’s Duratrac tires as far as the design is concerned. The trailrunner has a nice and aggressive all-terrain tread pattern, the middle trail grapplers are much rougher and longer-lasting than the previous models. These tires have very deep treads and the treads have small slits in them that help keep the mud and gunk out and also reduce road noise. They are very durable and will help you undertake some serious off-roading.

About the cooper AT3

The AT3 line by Cooper consists of three different tires, the Cooper discoverer At 4s, AT LT, and AT XLT.

Each one of these three tires serves a different purpose. The AT3 4s, which is the most commonly used amongst the three, is a light-duty all-terrain tire suitable for vehicles like the Ford Expedition or the ford f-150.

It is designed to perform well in snow and light off-roading conditions whereas the AT3 LT is more suitable for your heavy-duty vehicles and comes in much bigger sizes. It is great for vehicles like the ford f250 and the ram 2500 HT.

Then comes the At3 XLT which is the biggest tire among the three of these. It is designed for some of the more chunkier vehicles like the Chevrolet 2500/3500 and rams 2500/3500, however, one of the main purposes of these tires is to fit the jeeps that are lifted and modified in order to upsize.

Goodyear Wrangler Trailrunner AT and Cooper AT3 comparison

Dry and wet performance

The all-terrain pattern on the Cooper AT 3 is made up of a silica-based tread compound that ensures a secure grip in tough terrains.

In addition to some serious off-roading capabilities, the five-rib open design on this tire provides great wet and dry performance.

The Wrangler trailrunner has soft saw blocked edges that provide all-season traction on and off the road.

Each interlocking groove has several multi-angled sides that are there to provide added traction in dry and wet conditions.

Snow traction comparison

The Cooper AT3 performs quite well in slippery conditions. It has zig-zag sipes in the grooves that create biting edges which provide added traction on slippery terrains.

It has a special snow groove technology built into it to provide better snow traction. The grooves have sawtooth ridges that capture snow and lock it into the treads which adds traction and handling in the snow.

Similar to the cooper AT3 the wrangler, trailrunner also has sawtooth block edges which in combination with the multi-angle sipes help provide more traction in wet and slippery conditions.

Although it doesn’t lock the snow into the tire which puts it at a disadvantage against the Cooper AT3 when it comes to snow traction, the rugged stepped shoulder makes up for that by providing added traction in deep mud and snow.


The Cooper AT3 is engineered to make it as durable as possible.

It consists of a durable two-ply polyester casing, a single-ply nylon reinforcement, and two high-strength steel belts that further increase the durability and handling along with providing high-speed stability.

The Goodyear wrangler trailrunner has Large tread blocks that interlock to make the tire more durable.

They also have zigzag sipes on each groove which create vibrations as the tires spin and get rid of mud, snow, and gunk that gathers in the deep treads of the tire.

Noise comparison

Every all-terrain tire behaves and sounds different on the road. Most of them are built to facilitate off-roading which makes them quite noisy on the road, however, if you don’t want road growl or an obtrusive noise coming into the car as you drive the car, the Cooper AT3 is a good choice because it has whisper grooves in between the outboard tread blocks that help reduce noise.

The treads on the wrangler trail runner AT have been designed to minimize road noise and they do a pretty good job, however, the raised square tread blocks still produce considerably more noise than the cooper AT3.

Hydroplaning comparison

The cooper AT3 has deep aqua vac channels and wide lateral notches that are engineered to get rid of the water from the contact patch and prevent aquaplaning.

In other words, no matter how difficult the terrain your driving on is, these tires will not slip and will give you maximum control over your vehicle at all times.

Cooper AT3 takes the lead when it comes to hydroplaning because the Goodyear Wrangler Trailrunner doesn’t have a dedicated aqua vac channel to get rid of the water which makes it more susceptible to hydroplaning; however, the interlocking treads and the multi-angled sipes on the grooves do a pretty decent job at resisting hydroplaning.

Tread life comparison

The Cooper AT3 has the added feature of a ‘wear arc technology’ which reduces the pressure between the tyre and the road so it stays a bit flat to balance out the pressure.

It also has ‘stone ejector technology’ which gets rid of any gunk that might accumulate in the treads which prolongs the tread life and helps the tire last longer.

The wrangler trailrunner has high side walls, strong treads, and tough middle trail grapplers.

The treads are interlocked to each other which prolongs the tread life. Plus, the sipes are there to get rid of the gunk that gathers over time, so as far as the tread life is concerned, this tyre is well covered to last for quite a long time.

The final verdict

At the end of the day, it all comes to personal preferences. No doubt both of these tires are just as good as each other, which is why they are the two best all-terrain tires in the market right now.

If you’re looking for a tire that does well both on and off-road without making too much noise, you should go with the cooper AT3, however, if your looking for a tire that gives you better dry traction, then Goodyear wrangler trail runner AT is the better option.
