The Discoverer STT PRO is Cooper's Off-Road Maximum Traction light truck tire developed for the drivers of pickup trucks, Jeeps and SUVs who want confident, go-anywhere traction without sacrificing on-road performance. The Discoverer STT PRO is designed to provide impressive off-road capability combined with acceptable levels of on-road traction and civility.
Beginning with a robust, chip- and tear-resistant compound, the Discoverer STT PRO is molded into an aggressive, high-void tread pattern. Deep starting tread depths and alternating cleats and scoops in the shoulder lugs enhance traction in mud and other soft terrain, and mud release dimples help the tire self-clean. Anti-stone retention ribs at the base of the tread grooves eject small rocks to assist with preventing punctures due to stone drills. Wide lateral and circumferential channels aid hydroplaning resistance, and in-block siping creates additional biting edges for improved grip in slippery conditions.
The Discoverer STT PRO utilizes Cooper's Armor-Tek3 Construction technology, which features a robust, three-ply polyester casing to improve puncture resistance. Two wide, strong steel belts support the tread and are reinforced by a single nylon cap ply.
While Off-Road Maximum Traction tires, which are often called mud tires, are branded with the M+S symbol and able to churn through deep snow, their typical oversize applications and the relative absence of snow-biting sipes in their large lugs can challenge their on-road wintertime traction on packed snow and icy surfaces.
The Cooper Discoverer STT Pro brings capable, backcountry traction to the table, but does it have what it takes to compete on the road where many of its rivals are also built to perform?
