Let’s move on from the introduction phase to the primary information of Cooper Discoverer AT3 4S. In this review, we will take you through the pros of Cooper Discoverer AT3 4S along with its cons. Also, we will try to reveal details to give a clear picture of whether you should buy it or not. 


  • All-season and all-terrain tire

There may be a few complaints about Cooper Discoverer AT3 4S premature wear off of tread, but other than that, there is nothing that anyone has ever complained about. The issue has been resolved by backing the tire with a 65000 miles treadwear warranty. If it does not fulfill your needs, you can return it without costing any money. The tire is worth every buck spent due to its durable design and comfortable drive, providing continuous satisfaction.

Design and technology of Cooper Discoverer AT3 4S

Advanced technology and tread design patterns differentiate premium-quality tires from low-quality tires. Sidewalls and tubes play a role too, but these are essential for building any premium tire. Experienced engineers manufacture Cooper Discoverer AT3 4S tire after following every procedure to make it a comfortable and safe tire to run on any conditions of the roads. 3PMSF is a tag mostly winter tires miss to gain sometimes; with patented saw-tooth technology, it runs phenomenally on snow terrains; that is why it has the tag issued on this tire.

The small sipes give excellent control and stability on all terrains with the help of zigzag sipes, which also protect the tire from stone retention and drilling by giving optimal traction on drylands. The tire also features aqua-vac channels from deep grooves to resist hydroplaning and deliver a safer drive in the rain.

There are many other deep features involved in the tire that are hard to understand by a regular person. These are some of the main features that every other buyer wants to find in their tires. The rubber and material used to manufacture this tire are also world-class. That is why it runs longer than other all-terrain tires. 

Competitors analysis

Many other brands compete in this category. But the two competitors that we choose are based on comparable prices and features. “Hankook Dynapro AT-M” “Firestone Destination A/T2,” and the Cooper Discoverer AT3 4S have little ups/downs in prices. Still, the main difference is each of their performance. First of all, both competitors give 10000Miles less treadwear warranty, which raises a question about their tire durability. The Firestone destination comes with a 3PMSF certificate, but Hankook Dynapro lacks it. We are not criticizing any tire brand; we are just creating a difference that gives the most value. Each of these brands is well known and has excellent quality tires in their product line. 

Performance Analysis

On road ride

This versatile tire provides confident traction and grip in wet and dry road conditions. The tire tread blocks and sipes contact with the ground properly which stabilizes the ride while allowing proper performance in all-season conditions. Also, the shoulder blocks are helpful on fast tracks for smooth cornering, even at high speed. Four circumferential grooves allow the tire to resist hydroplaning and deliver proper grip and smooth ride in wet and rainy conditions. 

Off terrain performance

This all-terrain tire provides smooth performance on off-terrains as well. The individual tread blocks improve the tire grip with proper traction in mud terrain. Also, the tread blocks clear the mud from its tread for proper performance and a smooth ride in mud terrains. As this tire is 3PMSF certified, it delivers confident performance in the winter seasons. The zigzag sipes on tread blocks provide extra biting edges which improves tire grips and brakes in light and heavy snow conditions.

The tire is one of the most comfortable tires in the all-terrain tires category. It delivers a quiet and smooth ride in any condition of the road. Along with quiet treads, this tire tread contacts evenly with the ground, which also improves comfort whether it is on road dry conditions or snow terrain rides, the tire delivers a comfortable ride all year round.
