Discoverer At3 4S

The Cooper Discoverer AT3 4S is built for drivers who need one tire that can handle daily commuting, weekend adventure, and unpredictable weather. Designed for trucks, SUVs, and capable crossovers, this all-terrain, all-season tire offers versatility that fits a wide range of driving needs. Whether you’re upgrading through a wheel and tire package or replacing your complete tire set, the Discoverer AT3 4S provides dependable traction and stability for both on- and off-road use.

This model features Cooper’s Adaptive-Traction™ Technology, which improves grip across changing surfaces—whether navigating rocky trails, wet pavement, or loose gravel. Deep Aqua Vac™ channels help reduce hydroplaning during heavy rain, while the tread’s 5-rib pattern delivers balanced traction on dirt and asphalt. The Snow-Groove™ design enhances biting edges for superior snow performance, earning the tire the Three-Peak Mountain Snowflake (3PMSF) certification for severe winter service. The durable radial construction and optimized tread compound work together to promote long tread life, backed by a 65,000-mile warranty.

Despite its rugged capability, the Discoverer AT3 4S remains comfortable on the road. Its tread design limits road noise for a quieter cabin, and the stable tread blocks support confident steering and braking during everyday driving. Available in sizes ranging from 15" to 22", it fits many popular light trucks and SUVs. For drivers seeking year-round traction, off-road confidence, and genuine winter capability in one tire, the Cooper Discoverer AT3 4S delivers standout performance. Call 320-247-6160 for expert help.
