Cooper Discoverer AT3 LT All-Terrain All-Season Tire Key Features:
Reliable all-weather traction
Exceptional all-terrain performance

Longer-lasting tread life
Quiet and comfortable driving experience
 
Product Overview:
The Cooper Discoverer AT3 LT is an all-terrain, all-season tire specifically designed for light trucks, delivering impressive performance both on and off-road. Backed by a 60,000-mile treadwear warranty, this tire combines durability, versatility, and year-round reliability to tackle any journey with confidence.
 
Year-Round All-Weather Traction
Built with a durable silica-infused compound and an advanced five-rib tread design, the Discoverer AT3 LT excels in dry, wet, and winter conditions. The silica compound maintains flexibility in low temperatures, ensuring reliable grip in cold weather. Additionally, the zigzag tread grooves efficiently disperse water and slush, minimizing the risk of hydroplaning and improving safety on wet roads. These features guarantee consistent traction across changing weather conditions.
 
Superior All-Terrain Performance
Whether you're navigating muddy trails, loose gravel, or rocky surfaces, the Cooper Discoverer AT3 LT is built to perform. The staggered tread blocks and alternating scoops enhance grip and traction on soft, loose, and uneven terrains. Stone ejecting ledges prevent rocks and debris from becoming lodged in the tread, reducing the risk of damage and maintaining a clean footprint for optimal performance in challenging environments.
 
Even Wear for Longer Tread Life
Equipped with Even Wear Arch Technology, this tire evenly distributes driving forces like acceleration, braking, and cornering across the tread. This balanced pressure prevents irregular wear patterns, significantly extending the tire’s tread life. With a reinforced steel-belted internal structure, the tire maintains its optimal shape under heavy loads and high driving pressure, ensuring both durability and dependable performance over time.
 
Enhanced Handling and Control
The reinforced construction and strategically balanced tread design deliver stable steering response and improved handling precision. The tire maintains consistent road contact, allowing drivers to experience quick and accurate steering feedback, even on uneven or rugged terrain. This improved stability ensures confident control, whether on the highway or navigating tricky off-road trails.
 
Quiet and Comfortable Ride
Despite its rugged performance, the Cooper Discoverer AT3 LT offers a surprisingly quiet driving experience. Featuring Whisper Grooves Technology, the tread pattern minimizes road noise by redirecting airwaves and preventing soundwave vibrations. This creates a sound barrier effect, reducing cabin noise and providing a serene driving experience, no matter the terrain or speed.
 
Built for Durability
The two-ply polyester casing and twin steel belts reinforced with a nylon ply ensure the tire maintains its shape and resists deformation under heavy loads and off-road driving pressures. This structural integrity not only boosts longevity but also ensures a safer and more dependable driving experience on both paved and unpaved surfaces.
 
The Ultimate All-Terrain Tire
The Cooper Discoverer AT3 LT combines year-round traction, exceptional off-road capability, durability, and ride comfort, making it the ideal choice for light truck owners who demand reliability in all conditions. Whether you're hauling heavy loads, tackling rough trails, or cruising the open highway, this tire is engineered to deliver performance, control, and lasting value every mile of the way.
 
Manufacturers recommend changing tires every 10 years. As long as tires are properly stored before they are sold, the year of their manufacture will not shorten their service life.
