The Cooper Discoverer All-Terrain is an all-season all-terrain tire for pickups and SUVs, here in 275/65R18 with a 116 load index and T speed rating. It carries a 60,000-mile treadwear warranty in SUV sizes and 55,000 in LT sizes, and uses Sound Barrier Walls in the shoulders plus a repeating pitch sequence to quiet the highway ride. Silica compound, circumferential grooves and dense siping handle wet roads, while snow grooves and stone ejectors cover winter and gravel. It sits among the value-priced all-terrains: quieter and cheaper than aggressive mud-terrains, but less grip and durability than premium rivals like the BFGoodrich KO2 or Falken Wildpeak AT3W.

Owners rate it well overall, calling it a quiet, comfortable all-terrain for the money with good tread life. Complaints center on wet traction and noise as the tread wears.
The Cooper Discoverer All-Terrain 275/65R18 116T All- Terrain Tire has a 60K (SUV) 55K (LT) Treadwear Warranty. The tread design and internal construction helps the tire fight uneven wear to attain treadwear warranty. Sound Barrier Walls in the shoulders of the tire help keep tread pattern noise to a minimum. Repeating pitch sequence helps provide a smooth ride. Silica tread compound helps the tire grip the road in wet weather. Circumferential grooves and increased siping in the tread design help push water out of the tire's way for better wet handling. Snow groove technology helps bite into snow providing confidence in winter driving. Similar to its predecessor, the tread pattern kicks out stones with the stone ejectors (in the intermediate grooves). Stone barriers keep stones from drilling into tires. Tread compound delivers off-road performance on unpaved roads.
