About this item

Product details

Before purchasing tires, make sure to use our Tire Finder to select the right fit for your vehicle.

The only constant in life is change. This is especially true when you’re driving. Whether you’re running errands or going camping, you need to be ready for every curve and bump—and so do your tires. The Cooper® Discoverer Road+Trail™ AT tire was built with increased durability, stability, and traction to handle what the road throws your way.

EnduraGuard Design
A durable internal construction helps the tire keep its shape when driving over rough surfaces, giving you a more even wear across the tread.

Traction Shoulders
The continuous tread pattern extends over 50% further down the sidewall than the predecessor, and the angled design is twice as thick, providing more area to grip soft or uneven surfaces.

Thick, Rugged Tread Blocks
Interlocking tread blocks help provide the grip and consistent control you need on uneven terrain.

Three-Peak Mountain Snowflake Designation
Tires designed for use in severe snow conditions and meet specific snow performance test requirements.

Smooth Ride

Good Quality tires and I feel like I am driving a fresh off the show room car as the ride is so smooth on a 10 year old Jeep Wrangler

Cooper on a 2022 Jeep Gladiator

Had them installed on a Jeep Gladiator for about a month. Had stock Bridgestone Dueler HT with about 40,000 miles. They were smooth riding tires. I bought Cooper because of other reviews on the tire performance and pricing. Also, they’re made in the USA. To date I am very pleased with the purchase. Ride is good, look is good, and did I mention they are made in the USA.
