Cooper is a long-established American tyre maker with roots in Akron, Ohio, that later settled in Findlay, Ohio and built its business around the replacement market rather than original-equipment fitment. It is best known for its Discoverer all-terrain range and Zeon performance line, and suits SUV, 4x4 and light-truck owners seeking dependable tyres at accessible prices. Since 2021 it has been part of Goodyear.
Cooper's most aggressive mud-terrain tyre, built for extreme off-road traction with usable on-road manners.
The Discoverer STT PRO is Cooper's most extreme off-road pattern, engineered for trucks, SUVs and 4x4s that spend serious time in mud, sand, rock and loose ground. Its high-void tread, scoop-shaped lugs and sidewall biters dig in for grip and self-clean as they turn, while Armor-Tek3 three-ply construction adds puncture resistance for rough terrain. An alternating tread rib layout keeps things settled and reasonably quiet on the road between trails.
- Aggressive high-void mud-terrain tread for deep mud, sand and loose ground
- Armor-Tek3 three-ply construction for added puncture and impact resistance
- Sidewall biters and scoop-shaped lugs for extra bite over rocks and soft surfaces
- Anti-stone retention ribs that eject trapped stones and resist drilling
- Alternating 3-2 tread ribs to steady on-road handling and curb noise
