About This Tire

Winter driving demands exceptional traction, and the Cooper Discoverer Stronghold AT brings serious snow-gripping capability to SUV and truck owners. This LT265/70R18 all-terrain tire earns its Three-Peak Mountain Snowflake certification through textured shoulder edges that bite into snow and ice. What sets this tire apart is Cooper's 3D-sipe technology combined with wide open grooves that grab and release soft surfaces effectively.

From a durability standpoint, the Stronghold AT resists cracking, tearing, and tread rounding while preventing stone retention. With a substantial 16mm tread depth and 3,525-pound load capacity, this tire brings quality engineering to drivers who need reliable performance across challenging terrain and harsh weather conditions.

★★★★★5.0 out of 5 stars Great Tires

I first bought a set of these tires for my 2017 Ram. They ride great and traction in rain and snow is excellent. Noise is very minimal on my Ram for the deep tread. So I just received a set for my 2023 Jeep. Can’t wait to get these installed and see the difference in handling and control.
