Upgrade your truck or SUV with the Cooper Discoverer ATP II LT285/75R16 126R E1 RWL, an exclusive all-terrain tire built for pickups and SUVs that need confident off-road traction, wet-road control, and steady highway manners. This LT285/75R16 Discoverer ATP II is a popular fitment for select Jeep Wrangler, Toyota Tacoma, Toyota 4Runner, Ford F-250, Chevrolet Silverado 2500HD, Ram 2500 models, plus similar heavy-duty pickups, work trucks, towing setups, and trail-ready SUVs using 16-inch wheels.
Best for: work trucks, overlanding builds, and weekend adventure vehicles that need year-round all-terrain confidence with LT-rated strength for towing, hauling, and rough-road use, especially in a LT285/75R16 size with 126R E1 capability.
Why choose the Cooper Discoverer ATP II in LT285/75R16?
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.
