Cooper Discoverer STT - All Season On/Off-Road Maximum Traction tire
Armor-Tek3 Carcass Construction The heavy duty carcass is constructed of two radial polyester body plies and one angled polyester body ply to deliver 3 plies of protection for superior resistance to impact breaks and bruising. Super Traction Tread The computer designed, non-directional tread employs a combination of features including deep buttress lugs, notched and scalloped shoulder lugs, and a unique center traction zone to create a bold, aggressive tire for tough off-road applications. Tapered Stone Ejectors An integral stone ejector rib extends down from the center lugs to the buttress blocks to help prevent stones and debris from lodging between the tread elements while contributing to the overall soft surface traction. Rim Flange Protector Strategically placed in the lower side wall area, this feature helps protect the wheel and tire from hazards in off-road driving conditions while enhancing appearance.
  • 'Armor-Tek3®' carcass is constructed of two radial polyester body plies and one angled polyester body ply to provide 3 full plies of protection for superior resistance to impact breaks and bruising.
  • Scalloped shoulder lugs offer superb traction in soft surface applications and additional gripping power in off-road applications.
  • Resistant tread compound rim flange protector helps resist the cutting, tearing and chunking commonly developed in extended off-road applications. Strategically placed in the lower side wall area, a raised rim protector helps protect the wheel and tire from hazards in off-road driving conditions while enhancing the Discoverer STT's appearance.
  • Super traction tread employs a combination of features including deep buttress lugs, notched and scalloped shoulder lugs, and a unique center traction zone to create a bold, aggressive tire for tough off-road applications.
  • Deep buttress lugs - the aggressive tread design extends far down the sidewall of the tire to enhance its soft surface traction and also provide additional 'bite' and impact protection in off-road applications. The unique recessed Cooper knight's head on the raised alternating buttress blocks enhances the cosmetic appeal of the Discoverer STT.
  • An integral tapered stone ejector rib extends down from the shoulder tread lugs to the buttress blocks to help prevent stones and debris from lodging between the tread elements while enhancing the overall soft surface traction of the Discoverer STT.
