Better for Trails. Finding the perfect combination of comfort and performance when looking for new rubber can be a challenge. This Cooper Discoverer A/T3 Tire has taken out the guess work from the process. Featuring a broken center rib, this tire improves soft surface traction without sacrificing handling. Taking your Chevy Silverado out on your favorite trails is easier when outfitted with this A/T3. Thanks to its aggressive 5-rib all-terrain pattern and dual draft tread element walls, you'll get better traction and reduced stone retention and stone drilling.

Tough Rubber. The A/T3 Tire incorporates a silica based tread compound that improves cut and chip resistance on rocky or gravel terrain. Lateral groove protectors further reduce the chance of stone retention and stone drilling, protecting your treads.

Improved Wet Braking. Manufactured with high-silica compound, this Cooper Discoverer A/T3 Tire provides improved wet braking capabilities on the road or on the trails. The interlocking lateral groove tread is self-cleaning and establishes superior traction in the rain, snow, sand or mud.

Application. This Cooper Discoverer A/T3 Tire is designed for use on any 1999-2020 Chevy Silverado model. Please select your proper tire sizing from the options above. Sold individually.

      Would this tire size 275/70R18 on a 18x9.5 rim fit into the factory spare hanger under the truck?

          Review from Cooper Discoverer A/T3 Tire (Available From 31 in. to 35 in. Diameters)

          If you want the best tire for the buck!!

          I have always trusted Cooper Tires... Never had a reason not to... I have these on my 14 Sierra All Terrain, and there isn't another tire made that can beat them... Their QUIET, even at 35000 miles, Wear is excellent for a heavy truck, and I rotate and balance them every oil change (5000) miles... I live in the desert, and have yet to have any complaints about their performance... They look great, and on my 20 inch aftermarket wheels, I went from 275 to 305's....
