Built with durability in mind, the Cooper Discoverer Stronghold AT SUV and Truck Tires tackle difficult terrain to help your vehicle get the job done. It outperforms the Toyo Open Country A/T III in dirt and wet road handling, and when stopping on snow covered roads.* Tough jobs demand tough tires, and the Stronghold AT delivers the traction you need when it matters most. Wide open grooves in the tread grab and release soft surfaces, while Cooper's 3D-sipe technology helps to provide stability. This all-terrain tire provides grip and traction for the life of the tire. These tires resist cracking, tearing, and rounding of the tread, and prevent stones from getting stuck in the tread. Textured edges on the shoulders of the truck and SUV tire grab into snow to help provide traction in harsh winter conditions. The Cooper Discoverer Stronghold AT is protected by a 60,000 Miles Limited Treadwear Warranty. Cooper Tires offers a 45-Day Test Drive to test out your new tires. We've spent over a century building quality tires that are made to last. Incredible performance, reliable safety, and a price that won't break the bank. That's what you can expect from a Cooper Tire. *Based on internal testing comparing Cooper Discoverer Stronghold AT (LT275/65R18) to Toyo Open Country A/T III (LT275/65R18) on a 2020 Chevrolet Silverado 2500 HD.
