The Discoverer STT PRO is Cooper’s most advanced, extreme tire to date! The Discoverer STT PRO provides exceptional traction and performance in some of the harshest terrains on Earth. The distinctive tread design and compound provide remarkable on the road performance without sacrificing off-road traction. 3-Ply Armor-Tek3, silica tread compound, aggressive 3-2 center rib design, side-biters and more, all wrapped up in Cooper’s advanced mud terrain tire. Push the Discoverer STT PRO to the limits and you’ll “discover” what your vehicle is truly capable of!
“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.
Provides perfect control over winter roads. An SUV and 4x4 vehicle tire, the Dynapro I’cept provides 9% better braking performance than existing products, allowing for powerful driving even on snowy roads.
Wide Tread Width
The application of a wide tread width enhances snow and ice handling.
In addition to providing superior dry and wet handling, center edge effects offer outstanding snow and ice grip.
Center Step Tie Bar
Prevents shaking of the center block for greater ice braking performance.
4 Straight & 2 Zig-Zag Grooves
4 straight grooves channel away water for superior traction on wet roads while 2 zig-zag grooves offer tenacious grip on snowy surfaces.
Kerfs are connected to provide better drainage when snow has partially melted on the roads.
Vertical Serrated Groove
Serrations along the groove wall ensure improved traction on snow.
Cross Block System
Tread blocks are fitted together at an angle for better driving control and braking on icy roads.
Grooved walls provide the top snow edge effect.
Idealized Foot Shape for Braking
The optimal foot shape for maximum braking performance is derived by simulating the ratio between contact width and length. With a greater contact area compared to existing products, Dynapro i*cept boasts improved braking on snow and ice-covered roads.
