Tire and Wheel Size

by ckatteberry

I have a 2009 Chevrolet Silverado 2500HD 4×4 Club Cab Regular bed. I want to replace the stock tires and wheels but do not want to put a lift on the truck. What is the biggest size tires I can put on, and what size wheels are recommended?

Hi ckatteberry

The tires your are running are probably 245/75/16 which is the same as 30 inches.

You should be able to put up to 33 inch (285/75/16) tires without too much problem (perhaps a slight rub against the plastic under the bumper), even 35 inch if you are prepared for a possible sheet metal cutting

The best recommendation is to confirm this with your dealer – especially about the warranty.

As for the wheel size – you are limited by the disk brakes to you can’t go smaller than 16 inch. I would not go bigger than that.

If you change to bigger tires you should also plan for a gear ratio upgrade on the axles…
