Why choose the Cooper Discoverer ATP II in LT245/75R17?
All-terrain traction: Alternating shoulder scallops and wide off-road shoulder tread blocks help the ATP II dig into loose terrain like dirt, mud, gravel, and sand.
Wet and winter-road control: Wet Grip Grooves and Snow Claw technology help support grip on rainy pavement, slushy roads, and light winter conditions.
Durability for truck use: Stone Ejector Ledges help reduce stone retention, while rugged shoulder lugs add traction in aired-down driving and help resist damage away from pavement.
Highway stability: A solid center rib, stable tread area, interlocking sipes, and durable tread compound help deliver predictable handling and long-lasting all-terrain performance.
Comfort and warranty: Proprietary tread block sizing and spacing support a smoother, quieter ride, and the Cooper Discoverer ATP II is backed by a 60,000-mile manufacturer's treadwear warranty.
