Cooper Discoverer STT Pro



Cooper Discoverer STT Pro Tires

The Discoverer STT PRO is Cooper’s most advanced, extreme tire to date! The Discoverer STT PRO is a mud terrain tire that provides exceptional traction and performance in some of the harshest terrains on Earth. 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.

Features:

  • ARMOR-TEK3 Carcass Protection provides 50% more protection against impact damage than standard 2-ply tires.
  • The inner tread ribs alternating 3-2 pattern provides a number of significant performance benefits like: reduced road noise, increased stability and handling, superior soft surface (trail) and mud traction.
  • The “flex groove” provides a smoother ride by helping to dampen the impact generated by inconsistencies in pavement, potholes and gravel.
  • The Discoverer STT PRO features large, specially-designed cleats of rubber (side biters) on the shoulder area of the sidewall, to enhance traction and grip.
  • The asymmetrical scallops on alternating lugs direct mud into the mud scoops to allow the tire to pull through muddy terrains with ease.

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.
