Discoverer Stronghold At

Drivers who depend on their truck for demanding jobs and long mileage hauls need a tire that’s as resilient as their workload. The Cooper Discoverer Stronghold AT is engineered specifically for heavy-duty pickup trucks that face rough terrain, changing weather, and full-capacity towing. For anyone building a complete tire set that can handle gravel roads, highway miles, and winter storms with equal confidence, the Stronghold AT provides a dependable all-terrain foundation.

Its construction features wide, open tread grooves designed to grip into dirt and loose surfaces, while 3D-sipe technology helps maintain stability when traction matters most. The shoulder design uses scooped edges, deep grooves, and reinforced elements that enhance sidewall strength and help resist cracking, tearing, and tread rounding—critical advantages for drivers who regularly navigate harsh jobsite conditions. The radial casing and all-terrain rubber compound are built to manage heavy payloads, providing predictable handling whether the truck is unloaded or loaded to the max.

Winter performance is another standout. Every size of the Discoverer Stronghold AT carries the 3-Peak Mountain Snowflake (3PMSF) symbol, meaning it’s certified for severe winter conditions. Textured shoulder edges help bite into deep snow, while the tread pattern evacuates slush to maintain steering control and braking stability. With available sizes from 16" to 20", the Stronghold AT fits a wide range of modern work trucks and HD pickups, offering year-round toughness and long-mile confidence.
