Product Info

Discoverer AT3 LT

Built for drivers who split time between freeway miles, jobsite gravel, and rough back roads, the Cooper Discoverer AT3 LT is a heavy-duty all-terrain option with LT strength in every available fitment. The Cooper Discoverer AT3 LT tires are offered here in six load range E sizes, including 245/70-17, 265/70-17, 265/70-16, and 265/75-16, making it a smart fit for owners who need real load support and balanced all-terrain traction.

For pickups, trucks, and truck-based SUVs, this model is built around LT durability, a 60,000-mile warranty, and severe-snow capability with the 3PMSF/snowflake designation across listed sizes. Cooper also backs this tire with Even Wear Arc Technology for more even pressure distribution and Whisper Grooves Technology to help keep daily driving more composed on pavement.

At American Tire Depot, this tire makes sense for drivers shopping older heavy-duty trucks, midsize trucks, and body-on-frame SUVs that need confident towing, hauling, and year-round versatility.
