Description
Cooper Discoverer A/T3 4S 255/50R20 109H XL
OVERVIEW
The Discoverer AT3 4S tire from Cooper delivers off-road performance for light trucks and SUVs without giving up ride comfort, low noise, and road manners on the pavement. The Discoverer AT3 4S features a silica-enriched tread formulation with two steel belts, polyester cord plies, and a nylon reinforcement layer. Where the rubber meets the road, you’ll find an open five-rib all-terrain tread pattern with Aqua Vac channels to resist hydroplaning, Micro-Gauge zigzag sipes, and sawtooth block edges for traction in slush and snow. Backed by a 65,000 mile limited manufacturer tread life, the Discoverer AT3 4S is Three Peak Mountain Snowflake certified for use in moderate to severe winter weather conditions.
