Stepping up to 22.5″ wheels shows you aren’t afraid to make bold moves. Upgrading to a 6 wheel kit like this will land you in the driver seat of an extra 12,000 lbs of towing capacity. It also gets your medium duty truck up to dock height. Built with a 8 x 275mm bolt pattern, these wheels were made to improve your Chevy/GMC 4500/5500 or to replace you Class A Motorhome’s wheels.

This kit comes with a set of aggressive off road tires. Their open shoulder design and zig-zag center tread help deliver a long tread life and traction in wet or dry conditions. Tires come with a 6 year warranty and carries a casing allowance for 2 retreads.
