Discoverer AT3 XLT

Built for drivers who tow, haul, and still head beyond the pavement, the Cooper Discoverer AT3 XLT is a heavy-duty all-terrain option with a wide spread of LT and flotation sizes. The Cooper Discoverer AT3 XLT tires bring together on-road manners and off-road grip with fitments such as 275/70-18, 315/70-17, 32x11.50-15, and 35x12.50-20, making them a smart fit for truck owners shopping at Advantage Tire Pros.

For heavy-duty pickups, lifted trucks, and off-road SUVs, this model is available in LT and floatation sizes with load ranges C, E, and F to match everything from trail builds to serious towing setups. Some fitments are also snow-rated and carry a severe-snow 3PMSF designation, while the line is backed by a 60,000-mile warranty for added long-term value.

Cooper supports this tire with features like Rugged Traction Shoulders, Even Wear Arc Technology, Whisper Grooves, and stone ejector ledges to help with gravel roads, rough job sites, and mixed highway use.
