I have a 79 chevy K10 with a 3 inch body lift. I am looking at getting the new Pro Comp Xtreme Mud Terrain tire and i am not sure how big of tire i can get with out rubbing. Would a 35X12.50R15 fit with out any cutting of the inner fender or fender itself. Any advice on tire size or if the Xtreme Mud Terrain is a good tire would be much appreciated.  

a 76 k5 blazer i used to have had a 4 inch suspension lift and 35x12.50's on it. it would rub them when turning offroad on the rear edges of the front fenders. if you are going to stay with just the 3 inch body and dont wantto cut sty with a 33, and keep the sway bar hooked up and you should be ok.
