Features and Benefits

All-terrain tires resist harsh off-road conditions of mud, rocks, and stones thanks to their robust construction and reinforced carcass that provides the necessary strength to withstand challenging terrains. The Discoverer AT3 XLT promises to empower pickup trucks with the same rugged power.

• Sturdy off-road performance: The rugged traction shoulder design improves the aesthetics and also delivers great off-road traction. The Cooper tire performs really well on soft surfaces and mud thanks to its all-terrain tread design and advanced silica compound. The tread blocks and deep grooves help in the quick clearing of water, mud, and slush and avoid the risk of hydroplaning.

• Robust construction: The use of durable tread Technology ensures effortless hauling of heavy loads with protection against gravel and stones on the way. The presence of stone ejectors safeguards the tread from any stone drilling. Reinforced sidewall design ensures heavy loading isn’t troublesome for the tire as it efficiently absorbs the impact. The 10-ply construction further provides excellent durability.

• Great on-road handling: The Even Wear Arc ensures great handling and balanced on-road treadwear throughout the life of the tire.
