The Cooper Discoverer AT3 4S is a winter all-terrain tire for light trucks and SUVs.

The Cooper Discoverer AT3 4S light truck and SUV tires feature Snow Groove technology with biting edges that trap snow in the grooves for better traction on snow.

Superior Traction and Handling

Known for its on-road comfort and durability, the Cooper Discoverer AT3 4S has adaptive traction technology that provides excellent traction on smooth or bumpy roads in the worst conditions.

Patented Technology

Uniquely shaped, deep center grooves increase the tire's resistance which improves the tire's resistance to hydroplaning. A 5-rib pattern has been specially developed to optimize off-road driving and traction on wet and dry surfaces.
