Description

Cooper's Discoverer AT3 4S delivers off-road performance for light trucks and SUVs without giving up ride comfort, low noise or road manners on the pavement. It features a silica-enriched tread formulation with two steel belts, polyester cord plies and a nylon reinforcement layer. On the road surface, an open five-rib all-terrain tread pattern uses Aqua Vac channels to resist hydroplaning, plus Micro-Gauge zigzag sipes and sawtooth block edges for traction in slush and snow. The Discoverer AT3 4S is Three Peak Mountain Snowflake certified for use in moderate to severe winter weather conditions and is backed by a 65,000-mile limited manufacturer tread life.
