Discoverer AT3 LT

Built for drivers who split time between pavement, gravel, and demanding jobsite travel, Tucker Tire offers a practical all-terrain option for hard-working trucks and SUVs. The Cooper Discoverer AT3 LT tires are offered here in LT, load range E sizes such as 245/70-17, 245/75-17, 265/70-17, and 265/75-16 for drivers who tow, haul, and need dependable all-terrain traction.

Designed for pickup trucks, work trucks, and full-size SUVs, this model balances everyday road comfort with off-pavement durability. Every listed Tucker Tire fitment is LT, load range E, and severe-snow-rated with the Three-Peak Mountain Snowflake designation, plus a 60,000-mile warranty for added confidence through changing seasons.

Cooper supports this tire with Even Wear Arc Technology, Durable Tread Technology, Whisper Grooves, and a cut- and chip-resistant tread compound to help promote long wear, quieter driving, and traction on dirt, gravel, mud, wet pavement, and light snow.
