Cooper Discoverer AT3 review

We cannot miss out on Cooper on the list of well-known US-based premium tire manufacturers. Its dependable tires with functional technology are among the most favorite choices for all-terrain use, as you will see through this Cooper Discoverer A/T3 review.

Cooper Discoverer A/T3 Reviews

It is challenging to find an optimal tire that fits your SUV or truck and performs at its best both on- and off-road. The good news is you have the Cooper Discoverer A/T3 as your next potential option.

Cooper has balanced its tread design, so the traction level on both dry and wet highways is excellent. Moreover, it will deliver reliable and solid performance on a variety of terrains for a comfortable ride.

Besides the appealing tread pattern, this tire also features a 5 ribbed design, so that you can handle the vehicle better on-road with stability.

You may notice how the aggressive shoulders make this tire look much better and add more traction on normal surfaces at the same time. Around the tire’s circumference are thick grooves to boost its performance.

The main reason why the Discoverer A/T3 has minimal road noise and enhanced tread wear is its unique zigzag sipping structure.

Its grooves are important factors in minimizing stone retention on the truck tire’s surface. We are deeply impressed with its ability to self-clean, meaning your tire will always be fresh and clean on-road.

Its wet performance, in particular, is highly outstanding. The tire’s tread compound is silica-based for impressive wet weather use, free from slippage, and gives you confidence driving in such situations.

This Cooper Discoverer A/T3 tire comes in a wide variety of sizes from 15 to 20 inches in LT and non-LT ranges for your consideration. You will be glad to know it also has a warranty after 50K-mile riding.

Pros & Cons

Pros
  • Superior grip on wet and dry surfaces, even in the snow
  • Good traction on off-road terrains
  • Quiet tires on the highway
  • The self-cleaning function clears gravels from tread channels
Cons
  • Not ideal for driving in snow

Tire Drive Test

To sum up our Cooper Discoverer A/T3 review, we would say that this tire is a great value to consider, though it is not always the most popular option. We are stunned by its grip on wet and dry surfaces compared to other tires.

It did not matter if the terrain was on sand, mud, grass, gravel, or rock. This tire got us through with confidence. Of course, it is not a specialized unit for rock climbing, but its performance is amazing.

On the other hand, the Cooper Discoverer A/T3 does not work well in deep snow, causing you problems in accelerating and braking.

Overall, this model is well-balanced enough for all-weather, road, and terrain applications. It deserves a ranking as the top in its class.

    These were put on about 8000 miles ago. They have proven to be a great fit. These tires look fantastic wrapped around my raptor 17s and are quieter than the previous BFG KO2s. These XLTs still feel aggressive compared to Highway terrain tires, but they are much quieter than I expected. They are able to withstand both wet and muddy conditions. I am extremely happy with their performance so far. After I have worn the set for a year, I will be able to return and leave another review. I also want to give more feedback. They are fantastic on my 2010 F150.

    These tires have logged about 1,000 miles and I felt the need to review them. The stock Michelin AT tires were in my truck. They haven’t been much of a priority to me. They are useless if you drive on hard surfaces. I was looking for something with a more aggressive tread, but not so much road noise as to drive me crazy. These AT3 XLTs looked great and I was compelled to give them another chance due to the 45-day guarantee. Wow! These tires are quiet. These tires are quieter than my original tires. They still get the same mileage. They look great with the sidewall “teeth”. They look great and will last on my truck – unless they completely fall apart within the next two weeks. Great American-made tire.

    These tires were purchased for my 97 F-350CC. They were 7.3 and 12,000 miles since they were purchased 12 months ago. A lot of camping, wood cutting and logging on the single-track rough terrain and down dirt roads. They were used in snow, rain, and asphalt. I can pull 30ft. I haul 30ft. These tires are great and perform well in all weather conditions. They look fantastic and I have no complaints. I bought a set of tires for my son’s Jeep. He loves them and enjoys driving in the hills, rock crawling, etc. These tires are going to be my next purchase.

    These are for my 2500, which I use as my daily driver and for pulling the camper. These tires have performed well on snow, dry, and wet surfaces. They are more comfortable on slick surfaces than my old tires. The AT3’s made it easier to drive in winter conditions for a 3/4-ton daily driver in Montana. There is no tire buying regret here.

    This tire has been my daily driver for over 10k miles. For off-roading, I use a 285/60 10ply tire on my 4Runner. This tire is amazing, I’m sure! These tires are more suitable for off-roading or heavy trucks than the original design. They have exceeded my expectations in this category! They have exceeded my expectations in this category! The lowest was 3.5 ounces. They are very quiet and ride well. Balance is not worth it.
