About Cooper Tires 285/70 R17 Discoverer AT3 XLT 2026

The Discoverer AT3 XLT combines an aggressive all-terrain tread with features intended to make it manageable during normal road use. Drivers considering Cooper Tires for pickups and larger SUVs get Rugged Traction Shoulders for loose terrain, stone-ejecting ledges for gravel environments and Whisper Grooves designed to reduce tread-generated road noise.

Built for Mixed Road and Off-Road Driving

This tyre is significantly more terrain-focused than a conventional highway SUV tyre. Large tread blocks and aggressive shoulder elements provide biting edges for dirt, gravel, loose soil and muddy surfaces, while the tread remains structured for predictable behaviour on paved roads. The 70-profile sidewall also provides useful depth for rougher surfaces where very low-profile tyres would offer limited cushioning and wheel protection.

Heavy-Duty LT Construction

The official AT3 XLT specification for this size is LT285/70 R17 121/118S Load Range E. It carries a maximum single-tyre load of 3,195 lb, approximately 1,449 kg, at the specified maximum inflation pressure. This makes it substantially different from the P285/70 R17 117T specification found in the AT3 4S range. Buyers ordering through Dwbtyres should check whether their vehicle requires the heavier LT construction or the lighter P-metric alternative before purchasing.

Durability, Stone Protection and Tread Life

Cooper uses Durable-Tread Technology and Even Wear Arc Technology in the Discoverer AT3 XLT to support durability and more balanced contact pressure as the tyre wears. Stone ledges are incorporated into the tread to help eject trapped stones and gravel rather than allowing them to remain embedded between tread blocks. Cooper also backs the AT3 XLT with treadwear protection of up to 60,000 miles or 90,000 km under applicable manufacturer warranty terms.

Made for Trucks and Full-Size SUVs

Cooper Discoverer AT3 XLT LT285/70 R17 121/118S 2026 is most appropriate for pickups, work vehicles and full-size SUVs that genuinely need an all-terrain tyre. It provides more off-road capability and stronger load construction than a normal passenger SUV tyre, but that rugged design also means buyers seeking maximum road refinement alone may be better served by a highway-terrain product. Before you buy car tyres in UAE, verify that LT285/70 R17 121/118S Load Range E matches the vehicle's required load capacity and intended use.
