Discoverer AT3 XLT
Built for towing, hauling, and rough backroads, the Cooper Discoverer AT3 XLT is a truck-focused all-terrain tire that blends everyday road manners with reinforced off-road traction. The Cooper Discoverer AT3 XLT tires are a strong fit for drivers who want dependable capability from Tucker Tire, especially on pickups and lifted 4x4 builds that see pavement, gravel, mud, and jobsite use.
This lineup includes 11 active sizes, with modern LT options like 275/70-18, 285/65-20, and 315/70-17, plus classic floatation sizes such as 31x10.50-15 and 35x12.50-20. Load ranges C, E, and F are available across the catalog, and select sizes are snow-rated with 3PMSF coverage for added cold-weather confidence.
Cooper’s reinforced traction shoulders help improve boulder crawling and mud handling, making this a practical choice for work trucks and adventure rigs alike. If you’re ready to compare sizes or book service, Tucker Tire can help you find the right fit and get you back on the road with confidence.
