Cooper Discoverer STT Pro

Off-Road Mud Terrain

Cooper's most advanced extreme off-road tire to date, the Discoverer STT Pro provides truck and SUV drivers with true go-anywhere capability and performance in some of the harshest conditions they'll ever encounter.
The aggressively designed tread pattern features alternating 3/2 inner block elements for superior traction in mud and increased handling stability with reduced road noise.
Large side and shoulder lugs provide additional bite for outstanding traction in mud and on other loose surfaces.
Additional off-road traction is provided by the asymmetric scalloped cuts on alternating side lug elements which direct mud into specially designed scoops.
Cooper Tire's advanced 3-ply Armor-Tek3 carcass construction provides exceptional durability and impact damage resistance.
A tread compound engineered with silica provides resistance to cutting and chipping when driving in rocky or off-road conditions.
M+S rated for all-weather traction.
Available with Raised White Lettering (RWL) on certain sizes where noted.
The Cooper Discoverer STT Pro is available in many LT load-rated and flotation sizes, up to 37 inch diameter.
