Why Compare?

Both tires offer drivers all-terrain performance, but they both offer something different. It is important to understand these differences so that you can make an educated decision on which tire will be best for your needs. The Cooper Discoverer AT has a center rib that is surrounded by larger tread blocks. It has deep grooves which provide excellent traction when driving in loose gravel or debris on off-road surfaces.

The Adventurer A/T’s pattern features large vertical bars for more biting edges with less void space between them. It also has enough space to allow mud and debris to be pushed away from the tire’s footprint, preventing clogging of the tread blocks.

Sidewall Design:

While both tires have sidewalls that are reinforced for extra protection, the Discoverer AT’s sidewalls have a more aggressive design. It features thicker steel belts that run across the tire’s center to provide more stability on off-road surfaces.

The Adventurer A/T has less sidewall coverage than its counterpart which results in better handling and responsiveness on paved roads but leaves it vulnerable to sidewall damage. The Adventurer A/T’s sidewalls are made of a stronger rubber compound than that of the Discoverer AT, which reduces its ability to resist cuts and punctures. Still, it is softer on pavement for better responsiveness. Construction Material:

Tire Construction

The Cooper Discoverer AT3 has an all-steel construction with two steel belts and a nylon overlay. The rubber compound used on the Discoverer AT is one of the strongest in its category, allowing it to be more resistant to cuts, punctures, and tears than other tires.

The Cooper Adventurer A/T has an all-steel construction with two steel belts for extra reinforcement against sidewall damage while its rubber compound is softer on the road but not as strong in inclement weather conditions.

Tire Type

Both are all-season tires, which means that they can be used all year round. The Adventurer A/T is a more aggressive tire, which means it can be used in all weather conditions, while the Discoverer AT has better on-road performance and should only be considered if you are mostly driving on paved roads.

Protection From Punctures:

The Discoverer AT features sidewall protection to prevent against sharp objects that could pierce the tire’s casing causing an air leak or deflation. The Adventurer A/T also features sidewall protection.

Tire Size:

The Discoverer AT is offered the same size as Cooper Discoverer AT3 inches to 20 inches except for 19 inches. The Cooper Adventurer A/T also offers rim sizes between 15 inches to 20 inches except for 19 inches. Keep in mind, all rim sizes also have more different tire sizes on them. To find the perfect size, please check your car manual.

Warranty Mileage: 

The Cooper Discoverer AT3 is covered by a 60,000-mile limited warranty that protects you from road hazards for up to five years. The tire’s tread life expectancy also lasts around 50% longer than other competitive products!

Adventurer A/T comes with a Standard Limited Warranty. The Adventurer A/T is NOT protected by a Treadwear Protection Warranty. However, both tires offer a 45-Day Test Drive to test out your new tires.

Load Capacity: 

Cooper Discoverer AT3 tires are made of the radially reinforced, ultra-tacky compound and with a maximum tire load capacity of 1709 pounds to 2833 pounds and a maximum tire inflation pressure of 44 psi to 50 psi.

On the other hand, Cooper Adventurer A/T tires come in 36 tire sizes with a maximum tire load capacity of 2039 pounds to 3638 pounds and maximum tire inflation of 40 psi to 50 psi.

Tread Depth:

The Cooper Discoverer A/T3 has a tread depth between 13/32 inches to 17/32 inches. It is important to remember that the deeper your tire’s tread, the more you expose it to water and slush, reducing traction on wet road surfaces!

The Adventurer A/T has an even shallower tread depth of average 14/32 inches, the same as most passenger car tires. This makes it suitable for light off-road use but also means that you would need to replace your tire more often due to its lack of tread pattern!
