Discoverer At3 Xlt

The Cooper Discoverer AT3 XLT is built for drivers who expect real capability from their pickup—strength for towing, control on rough terrain, and confident traction throughout the year. As part of a complete tire set for half-ton and heavy-duty trucks, it combines all-terrain versatility with LT-rated toughness, making it a standout choice for hauling equipment, towing campers, or navigating unimproved work sites. With sizes ranging from 15" to 20", it fits many popular trucks and off-road builds while maintaining dependable on-road manners.

Cooper designed the Discoverer AT3 XLT with rugged traction shoulders that bite into mud, ruts, and loose gravel, improving stability and control on demanding surfaces. Its radial construction, available Load Range E fitments, and reinforced sidewall design help support heavy payloads without sacrificing durability. Even Wear Arc™ Technology distributes pressure evenly across the tread for balanced wear and predictable handling, while Whisper Grooves™ Technology reduces noise for a quieter ride—an uncommon advantage for a tire with this level of off-road grip. Stone ledges built into the tread eject debris before it can cause damage, extending tread life and preserving performance.

For winter driving, the Discoverer AT3 XLT carries the Three-Peak Mountain Snowflake (3PMSF) certification, validating its ability to perform in severe snow and slush. Drivers who want a wheel and tire package that works just as hard off the pavement as on it will appreciate the AT3 XLT’s blend of hauling strength, long-term reliability, and year-round capability.
