Cooper Discoverer Stronghold AT Tires

Cooper Discoverer Stronghold AT tires provide all-terrain grip, the ability to handle heavy loads and long highway hauling, and are winter capable with the Severe Snow Designation on all sizes. Designed for protection from demanding environments, solid traction, and with strength that lasts the test of time, Cooper Stronghold AT tires should be your choice to fit your heavy-duty truck. Select the appropriate size for your truck.

Key design features and benefits:

* Wide open grooves in the tread grab and release soft surfaces, while the 3D sipe technology helps to provide stability
* Strong shoulder design features, like scooped tread edges, wide tread grooves, and sidewall hook pattern, help provide grip and traction for the life of the tire
* Textured edges on the shoulders grab into the snow to help provide traction in harsh winter conditions
* Strategically designed tread lugs help to resist cracking, tearing, and rounding of the tread
* Ledges between the lugs help prevent stones from getting stuck in the tread
