The Cooper Discoverer All-Terrain is a three-peak-rated all-season tire for 4x4s and light trucks, sold here in LT275/70R18 load range E (125S). It pairs a silica compound and dense siping for wet grip with stone ejectors and stone barriers for gravel and dirt, and Sound Barrier Walls in the shoulders to quiet the tread. It is a value-focused alternative to premium all-terrains like the BFGoodrich KO2 and Falken Wildpeak AT3W: softer and quieter on pavement, but less aggressive in deep mud and rock. It suits drivers who mostly commute and tow with weekend trail and snow use.

Owners rate it highly overall, praising quiet highway manners, confident wet and snow traction, and even wear. Complaints center on a stiff ride in LT sizes and weaker deep-mud performance than more aggressive rivals.
The Cooper Discoverer All-Terrain LT275/70R18 125S 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.
