The Discoverer Road+Trail AT is Cooper's On-Road All-Terrain tire, built for the drivers of pickups, work vehicles, and SUVs who need a tire with the rugged durability to keep up with their active lifestyles. Engineered to tackle dirt, gravel, mud and the urban jungle, the Discoverer Road+Trail AT combines off-road prowess with agreeable on-road comfort and year-round traction. It even handles light snow well enough that it meets the tire industry's severe snow service rating requirements and earns the three-peak mountain snowflake (3PMSF) symbol.

Cooper Discoverer Road+Trail AT Callouts

A durable compound resistant to cutting, cracking and tearing joins with the Discoverer Road+Trail AT's next-generation all-terrain tread pattern. This design features rugged, interlocking tread blocks off-roaders expect working alongside Cooper's Road Glide Technology to provide a smooth, quiet experience on the pavement. The alternating scoop and cleat lugs in the shoulder, sporting a thick, angled design further down the sidewall, were created to find grip on rock, in thick mud or loose soil. Deep, circumferential grooves and wide, lateral notches improve resistant to hydroplaning. The interlocking center tread lugs provide stability on the road and snow, while zigzag sipes in the shoulders create the biting edges needed for traction in slippery conditions.

The internal construction of the Discoverer Road+Trail AT consists of a robust, two-ply polyester casing. A single-ply, nylon 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.
