Gm trucks dont have that big of wheel openings. You should have no problem running 33s with a leveling kit. If your gonna run 35s, I’d take a look into like a 4" lift at least. Also, if you are going with 35s have you thought about changing your gearing? I know I read on one of the forums about going with bigger tires screws with the allison tranny. You should take a look into it to be on the safe side. the rims are coming off my buddies truck whos also has a duramax/allison and only cranked up the torsion bars… they fit with little to no rubbing. he never had a problem with the tranny because of the tire size. but with his tuner, now thats another story… --- _[View the full topic](https://forums.speedlife.net/t/what-did-you-do-to-your-car-today/239557)._
