Discoverer AT3 XLT

Built for towing, hauling, and rough Utah backroads, the Cooper Discoverer AT3 XLT is a truck-focused all-terrain choice for drivers who split time between pavement and dirt. The Cooper Discoverer AT3 XLT tires are available at Burt Brothers Tire & Service in serious LT and floatation fitments, including 275/70-18, 315/70-17, and 35x12.50-20, with load ranges C, E, and F to match different builds and work demands.

A strong fit for full-size pickups, heavy-duty pickups, and modified 4x4 setups, this model is built for off-road control, heavy hauling, and dependable on-road manners for trucks that work hard during the week and explore on the weekend. Cooper’s Durable-Tread Technology, Stone Ejector Ledges, Even Wear Arc Technology, Whisper Grooves Technology, and Rugged Traction Shoulders help resist cuts, chips, and stone retention while supporting even wear and a quieter ride for the category.

This Burt Brothers Tire & Service assortment also includes some snow-rated sizes with the severe-snow 3PMSF mark, plus larger floatation options for lifted trucks and trail-ready rigs. Backed by a 60,000-mile warranty and robust LT construction, it’s a smart option for Utah drivers who commute, tow, and head into changing mountain conditions.
