About this item

Product details

The Cooper Discoverer All-Terrain 275/55R20 117T 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.

Don't cheap out on tires

Very very very high quality tires from a respectable brand. I noticed right away it's so much smoother and makes the truck look more aggressive with its sidewall design. Ordered from big blue mart and got it delivered at the automotive but they dont install on aftermarket rims so please be advised. Also if the app dont let you schedule an appointment for install just buy the tires first and after you pay you can schedule. But overall these tires are great they are owned by good year and made in america! So you know it's high quality!
