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.
'Superior on-and-off-road capabilities and rugged all-terrain performance.'
For Multi-purpose and off road 4x4 vehicles (50% on-road, 50% off-road).
The All Terrain T/A KO tyre is totally versatile and offers maximum driving pleasure on all types of path:
20% Tougher Sidewalls: Featuring race-proven CoreGard™ Technology to take on the toughest road hazards with confidence.(1)
CoreGard Technology:Tougher Sidewall Rubber: Split & bruise resistant sidewall rubber, derived from BFGoodrich's race proven Baja T/A®KR2 tire. Thicker, Extended Shoulder Rubber: Increased rubber thickness, extending down the sidewall to protect more of the critical sidewall failure zone. Advanced Deflection Design: Computer predicted object path design deflects protruding objects from snagging & splitting the sidewall.
Longer Treadlife On and Off-Road: To extend your adventure.(2)
Specially formulated tread rubber: optimally blended to reduce chip and tear for superior gravel road endurance. Advanced tire footprint shape: results in more evenly distributed stress, for longer more uniform wear. Interlocking Tread Design: provide increased tread block stability, for more even wear over the long haul Stone Ejectors: Rejects stone retention & provides extra tread cleanout protection against stone drilling.
Aggressive All-Terrain Traction: Exceeding RMA Severe Snow Traction performance requirements.(3)to confidently get where you want to go.
Side Biter Lugs: Protruding sidewall rubber blocks that provide increased mud, snow & rock traction, especially in aired-down driving situations. Mud-Phobic Bars: Raised bars in the shoulder tread area that helps to release compacted mud for enhanced traction in muddy and soft soil conditions. Serrated Shoulder Design: Staggered shoulder blocks that provide greater maneuverability in soft soil and deep snow conditions. Locking 3-D Sipes: 3-D active sipe technology, that provides more biting edges for significantly increased snow traction. 3 Peak Mountain Snowflake: Exceeds Rubber Manufacturer Association (RMA) Severe Snow Traction requirements.
(1) Improvement depends on the size of the tire purchased. 20% improvement based on internal sidewall splitting test results derived from a simulated sidewall aggression testing machine (patent pending US20120245859A1) vs. BFGoodrich® All-Terrain T/A KO tire in size LT265/70R17. Actual on-road results may vary.
(2) On-Road: Based on internal wear tests vs. BFGoodrich® All-Terrain T/A KO tire in size LT 265/70R17 Off-Road: Based on commissioned third-party gravel endurance tests vs. BFGoodrich® All-Terrain T/A KO tire in size LT 265/70R17.
(3) Snow: Based on third-party snow traction tests vs. BFGoodrich® All-Terrain T/A KO tire in size LT 265/70R17 using the ASTM F1805 Test.. Mud Traction: Based on internal subjective mud testing vs. the BFGoodrich® All-Terrain T/A KO tire in size LT 265/70R17.
