About This Tire

SUV and truck owners seeking reliable all-terrain capability will find the Cooper Discoverer Road + Trail AT delivers exactly what they need in the popular 275/55R20 size. The engineering delivers a continuous tread pattern extending 50% further down the sidewall with twice the thickness of angled designs, creating superior grip on soft or uneven surfaces. Where this tire shines is in its versatility - interlocking tread blocks provide consistent control across varied terrain while maintaining comfort on daily drives.

Thanks to connected center tread lugs and severe snow designation, winter driving becomes manageable even in challenging conditions. The asymmetrical tread design with 12/32nds depth resists cutting, cracking, and tearing that destroys lesser tires on tough trails. Cooper backs this confidence with a 65,000-mile tread life warranty, proving this tire offers dependable performance for drivers who demand both on-road comfort and off-road capability.

★★★★★5.0 out of 5 stars Awesome tires

Terrific tires. They are quiet for being all terrain and the price on Amazon was unbeatable. Cooper Tires are awesome. Had these installed on my 2016 Tundra.

★★★★★5.0 out of 5 stars Smooth, quiet ride for an all-terrain

This is our first set of Coopers. The ride was nice and smooth, grips great in the rain, tread is thick enough I’m not worried about small punctures while in the woods. They also are fairly quiet for an all terrain! We’ve got almost 20k on this set so far. I’ll update when it’s time for replacement.
