Cooper Discoverer STT Pro All-Season LT275/65R18 123Q Tire

The Cooper Discoverer STT Pro All-Season LT275/65R18 123Q Tire is the most extreme all-season, off-road tire Cooper offers to date, providing remarkable off-road performance without sacrificing on-road traction. The Discoverer STT Pro tire delivers best-in-class off-road performance, empowering the extreme off-roader to take on the toughest challenges. Patented Armor Tek3 tire technology adds strength to the tire sidewall, providing increased resistance to damage while driving over boulders and uneven, tough terrain. The Discoverer STT Pro comes with rubber formulated to combat shredding and damage from stones and off-road obstacles. The ROCK CLIMBER SIDEWALL gets max traction to help conquer even the toughest obstacles with deep ‘Climber Cleats’ and Flex Grooves built into the side of the tire that grip jagged rocks and power through thick mud. The MUD SLINGERS 2.0 are deep, wide trenches with additional notches throughout the tread combine to give you more grip to power through and help continuously clear thick mud from the tire. The EARTH DIGGERS can tackle tricky terrain with large blocks with alternating mud scoops that forcefully dig into loose dirt, sand or sticky mud. The STONE ARMOR TECHNOLOGY provides the ultimate durability with channels, ridges, and edges designed to help defend against sharp rocks and debris while expelling lodged stones.
