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 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

  • 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
  • Not ideal for driving in snow

Tire Drive Test

To sum up, 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.

    I’m delighted with my new tires! I put them on my 2010 F150 and they’ve proven to be great fit. With a quiet ride compared to their BFG KO2s predecessors, these XLT’s are rugged enough for just about any terrain – wet or muddy.

    After 8,000 miles the raptor 17″ look amazing so far and make me feel more aggressive than most highway models out there—all while being quieter that expected too. Now it’ll only get better when I come back this time next year to leave another review after release of wearing them down a bit first; can’t wait till then!

    After logging 1,000 miles in my truck on the stock Michelin AT tires, I began to explore options with a more aggressive tread that wouldn’t create too much noise. After settling on these American-made AT3 XLT’s and taking advantage of their 45 day guarantee – there was no looking back!

    Not only are they quieter than the originals but also provide excellent mileage without sacrificing style – boasting an unmistakable sidewall “teeth” look. Although time will tell if this choice proves fruitful for me long term whenever it comes to guaranteeing quality performance; so far, I’m very impressed!

    I’m exceptionally pleased with the superior performance of my tires for my 97 F-350CC. They’ve been amply tested in 12 months – even through a lot of camping, woodcutting, and rough terrain logging on single track roads!

    Not only do they provide incredible grip while pulling 30ft or hauling cargo over rain, snow, and asphalt alike; but I recently bought them for my son’s Jeep too — he loves ’em especially when rock crawling up hills. These top quality tires are definitely next on my list!

    I’m beyond thrilled with my new AT3s. They provide superb grip on snow, dry and wet surfaces – easily outperforming the tires I had previously on my 3/4-ton daily driver in Montana. Even driving during those snowy winter months has been such an easier experience! No tire buying regret here – these have proven to be a great investment for both everyday use as well as pulling my camper around too.

    I’ve been relying on this tire for over 10,000 miles of daily driving and off-roading my 4Runner. It’s a 285/60 10ply tire that has proven itself time and again; beyond the original design expectations! Not only is it quiet when you drive but balanced handling adds to its incredible performance – it truly lives up to all the hype.
