Thinking of stepping up to 22.5″ wheels? Upgrade your Chevy/GMC 4500/5500 stock 19.5″ x 6.75″ wheels up to the 22.5″ x 7.5″ for an extra 12,000 lbs of towing capacity. Going with these bigger wheels get your truck up to dock height. The 8×275 bolt pattern also fits most class A motorhomes.

With Toyo M647 tires you’ll have no limits. They have enough tread to get you out of the mud while still giving you a narrow straight tread to help you on the highway. The 16 ply tires can have a stiffer ride than most on the road, but with this closed shoulder design you’ll have low rolling resistance. They come witha a full 66-month limited warranty (on eligible claims).

Through years of innovation and advanced technology, Alcoa has proven itself as the leader in aluminum wheel manufacturing. Their forged aluminum wheels are both lightweight and durable. They increase your fuel economy and boost your productivity by requiring less maintenance. More vehicles on the road are fitted with forged aluminum wheels from Alcoa than any other brand. That is why when you think aluminum wheels, you think Alcoa.
