Cooper Discoverer STT Tires   –  

Cooper Discoverer STT Tires in LT295/70R17Now that we have the ReadyLift Silverado Leveling Kit installed on our truck we are going to add the Cooper Discoverer STT Tires in LT295/70R17 to our 2011 Chevy Silverado 1500. The LT295/70R17 are as large as you can install with this combination without doing additional modifications to the fender wells. Even then, the LT285/70R17 is a better fit but than, this truck is about finding the ultimate looks in a very drivable truck.

Off Road Traction Tires

Maximum traction for deep mud, clay and rocks; the Cooper Discoverer STT tires are designed with a very solid off-road capability combined with excellent on-road performance.
