Discoverer AT3 LT

Built for drivers who split time between pavement, gravel, and rough backroads, Cooper Discoverer AT3 LT is a practical all-terrain choice for hard-working light trucks and SUVs. The Cooper Discoverer AT3 LT tires deliver rugged traction for rocky and muddy roads while aiming for longer, more even wear. At Gunnell's Tire & Service Center, available fitments include 245/70-17, 265/70-17, and 265/75-16 for drivers who need dependable LT capability.

These LT load range E sizes are a strong match for heavy-duty pickups, midsize pickups, body-on-frame SUVs, and light trucks used for towing, hauling, jobsite travel, and rural-road driving. Every current Gunnell's Tire & Service Center fitment is snow-rated with a 3PMSF severe-snow-rated tread design, and Cooper backs this model family with a 60,000-mile warranty.

Key design details include Even Wear Arc Technology for balanced pressure across the tire, Armor Belt Technology for durability, Widening Siping Technology for added grip, and Water Evacuation Grooves to help maintain wet-road confidence.
