Cooper Discoverer AT3 4S

Equipped with Adaptive-Traction Technology™, the Discoverer AT³ 4S™ delivers a reliable grip on hard and soft surfaces under the most severe wet and dry conditions.

A Closer Look: The Discoverer AT³ 4S features a specially-designed Secure-Grip™ all-terrain tread pattern that allows you to head off-road with total confidence. Aqua Vac™ channels, uniquely-shaped deep center grooves, boost hydroplaning resistance by efficiently evacuating water from the tread. 3D Micro-Gauge™ Siping increases control and stability, reduces stone retention, and creates biting edges for maximum wet and dry traction. For the final layer of safety, patented saw-tooth technology traps snow in the tread, delivering outstanding winter traction, season after season.
