Why choose the Cooper Discoverer ATP II in 275/65R18?
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.

Customer Reviews
Very good value.
I ran KO2s on all of my trucks. I went out on a limb and tried the ATP II’s and wish I would have bought them sooner. Road noise is much less. The tread is still aggressive if in a sticky situation, but roll very well as a radial. I have them on a 19 Duramax, other than driving on my property or at the lake, locking in 4WD is seldom necessary. They look great too. I have a 3 on tread life because I only have about 8K miles so far.
They are doing quite well. I have hauled heavy and towed a large travel trailer with them, as well as driven on all types of roads and even handy dirt paths. Never felt any issues with traction or maneuverability. Very happy with them.
I would buy them again
