Product Info

Discoverer AT3 XLT

Built for truck owners who need confident towing, rough-road durability, and weekend trail traction, Cooper Discoverer AT3 XLT is a practical all-terrain upgrade at Automotive Outfitters. The Cooper Discoverer AT3 XLT tires are available here in 11 LT and floatation sizes, from 31x10.50-15 up to 35x12.50-20, with popular LT-metric options like 275/70-18 and 285/65-20.

A strong match for heavy-duty pickups, full-size pickups, and off-road SUVs, this model is built for hauling, towing, and mixed on/off-road use without giving up everyday drivability. Catalog fitments are LT only, with load ranges C, E, and F, available floatation sizing, and a 60,000-mile warranty that fits work-truck and lifted-build needs.

Cooper also highlights Rugged Traction Shoulders, Durable-Tread Technology, Stone ejector ledges, and Whisper Grooves to support off-road control and road manners. Some sizes are also snow-rated with severe-snow capability, including 275/70-18 and 31x10.50-15.
