The Discoverer Stronghold AT is Cooper's Off-Road All-Terrain tire, built for the drivers of pickups, crossovers, and SUVs looking for dependable traction off-road that can still offer some comfort on the pavement. Purpose-built to conquer dirt, gravel, mud, and the challenges of the city streets. It seamlessly blends off-road capability with secure on-road performance and reliable year-round traction. Notably, it handles light snow capably enough to meet the tire industry's severe snow service rating and displays the three-peak mountain snowflake (3PMSF) symbol.
The Discoverer Stronghold AT's specialized rubber compound forms the base of its next-generation all-terrain tread pattern. This design features tough, interlocking tread blocks for off-road action, while adjusting the individual lug designs for improved tread-life and resistance to irregular wear. The alternating scoop lugs in the shoulders join the distinctive hook sidewall molding to find grip in gravel or loose soil, while stone-ejecting ledges between each block keep rocks from getting lodged in the tread. Deep, circumferential grooves and wide, lateral notches fight against hydroplaning. Alternating textured edges lining the shoulder block interiors create biting edges needed for snow traction when winter strikes.
The internal construction of the Discoverer Stronghold AT consists of a robust, two-ply polyester casing. A single-ply, polyamide reinforcement above two high-strength steel belts further increases durability and handling response, along with providing high-speed stability.
Note: While non-winter tires featuring the three-peak mountain snowflake (3PMSF) symbol may provide additional longitudinal snow traction beyond what all-season (M+S) tires not bearing the symbol can deliver, they do not match the capability of a true winter tire in all adverse weather conditions.
