Get technical:

The Cooper Discoverer STT is an on and off-road mud terrain tire specially designed for drivers seeking strong traction, high performance, and durability. Ideal for off-road light trucks, SUVs, and pickups, the Cooper Discoverer STT does well on a variety of terrains while doing well on the road. The deep voids with channels that release suction make it self-cleaning so you don™t have to spend time washing your tires after every time you drive on muddy terrain. The siped lugs enhance traction both on and off the road by ejecting stones, mud, and snow while the 3-ply sidewalls enhance protection and resistance to puncture. Protecting your rims are the rim flange protectors. It also built with the Armor-Tek3 carcass constriction to enhance its resistance to impacts and bruising.
