Discoverer AT3 XLT

Built for towing, hauling, and rough access roads, Cooper Discoverer AT3 XLT is an all-terrain choice for Big Brand Tire & Service shoppers who want durability without giving up everyday drivability. The Cooper Discoverer AT3 XLT tires are offered in LT sizes such as 275/70-18, 285/65-20, and 35x12.50-20 for stock replacements and larger off-road setups.

This lineup is built for trucks, heavy-duty pickups, and off-road SUVs, with LT metric and floatation sizes across load ranges C, E, and F. Select fitments are snow-rated and carry the Three-Peak Mountain Snowflake designation, giving some sizes added confidence in winter conditions. Cooper-backed features like Rugged Traction Shoulders, Durable-Tread Technology, Even Wear Arc Technology, Whisper Grooves, and Stone ejector ledges help support traction, tread life, and off-road toughness.

Backed by a 60,000-mile warranty, Cooper Discoverer AT3 XLT tires are a strong fit for drivers upgrading work rigs, trail-ready builds, or daily-driven trucks. Start with Shop Tires, book installation through Schedule Appointment, or visit Locations for fitment help from Big Brand Tire & Service.
