About This Tire

SUV and truck owners seeking versatility without compromise will find their match in Cooper's Discoverer Road + Trail AT. Picture yourself confidently navigating from downtown commutes to weekend trail adventures, all with the same set of tires. This 255/55R20 tire features an innovative continuous tread pattern that extends over 50% further down the sidewall than previous designs, while the angled construction delivers twice the thickness for superior grip on soft or uneven surfaces.

On the road, you'll notice the interlocking tread blocks providing consistent control whether you're dealing with wet pavement or dry highways. The engineering delivers impressive snow performance through connected center tread lugs that maintain stability and traction in winter conditions, earning the tire its Severe Snow Designation. From a practical standpoint, the 11/32nds tread depth and asymmetrical design resist cutting, cracking, and tearing on tough trails while maintaining a surprisingly quiet ride on city streets. Cooper brings quality engineering to every aspect of this tire, backed by a 65,000-mile limited warranty and over a century of tire-making expertise.

★★★★★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.
