## Description

The Cooper Discoverer STT Pro All-Season 35X12.50R22LT 121Q 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.

Review: Best mud tire for the price. - This is a great looking tire. Unlike some other 35" mud terrains, these measure in true to size. They ride a bit rougher than stock rubber, but so does every other 10-ply tire which is your only choice in this size. I've run the Toyo M/T's before and I would say these are pretty much identical in terms of wear and ride quality. The only other tire I would consider would be a Nitto. They are more money, but supposedly a bit better according to most off-road shops I've spoken to. The attached images show these in a 35x12.50R22 on my 2015 F150 Platinum with a 6" BDS lift. I'm running a 22x10 wheel. You can see the difference compared to the factory tires.
