Discoverer At3 Lt

The Cooper Discoverer AT3 LT is engineered for drivers who demand strength, stability, and confident traction from their complete tire set—whether towing equipment, hauling heavy loads, or covering long miles on unpredictable terrain. Designed for ¾-ton and 1-ton trucks as well as capable SUVs, this LT-rated all-terrain tire adds durability and control to any wheel and tire package while maintaining dependable all-season performance on the road.

Built with Cooper’s Even Wear Arc™ Technology, the Discoverer AT3 LT distributes pressure across the tread for balanced wear and consistent handling throughout the life of the tire. Whisper Grooves™ Technology creates a noise barrier within the tread pattern, reducing road noise for a quieter ride—an advantage rarely found in heavy-duty all-terrain designs. Reinforced stone ledges help eject gravel and prevent embedded debris, while the tough radial construction and available Load Range E options support demanding workloads. The tire’s compound and block pattern deliver reliable wet traction, secure braking, and steady performance on dirt, gravel, and rutted surfaces.

For winter driving, the Discoverer AT3 LT stands out with its Three-Peak Mountain Snowflake (3PMSF) certification, confirming true capability in severe snow conditions. Available in popular truck sizes from 16" to 18", it’s an excellent fit for work trucks, tow rigs, and off-road-ready builds. Drivers who need durability without sacrificing comfort will appreciate the AT3 LT’s balance of everyday refinement and rugged strength. Call 320-247-6160 for expert help.
