I run 285/75/16 Bridgestone ATs (roughly 33") without so much as cranking the torsion bars, and I can't imagine running anything larger without a lift or cutting. Only thing I did was use a heat gun to slightly reshape a small part of the inner fender on the driver's front tire. And it rubbed only rarely…
I've always wondered exactly what the different size numbers equaled to in standard size. Example, 265x75x16. Does that equal a 31 with 9inch width and 16 rim? I know what the numbers mean but I dont know the comparison. Thank's Adam
35s (315s) will fit with some cranking and trimming, depending Chevy/GMC. if you have a metal (tin can) bumper, you will have to move it forward unless you want to cut it. the most important single factor is the backspacing on the wheels, absolute must to have at least 5.125" to have enough space, even then it is close. definetely not enough to run chains or do anythingn serious off road
I know that people say you can install "HUGE" tires without any cutting or cranking, but, the truth is: Chevrolet doesn't give us a wheel well to work with in the front for very large tires without a lift of some type!
I have posted a picture of my truck with H2's and 315X70-17's. In order to get it to stop rubbing I had to cut the front valance and the bumper even after installing the Spindles.
The back wheel wells are NO problem, Just the fronts.
