I'm running a bone stock setup right now and i'm looking at moving up to some 33's and a leveling kit for the front...i'm sure i will be able to clear these as i don't do any really hardcore offroading to where the flex would cause much rubbing but on the stock 17x7.5 rims can i run 33x12.5's and if so how much will they stick out past the stock flares and rub during a full turn? Any help would be appreciated and i'm trying to see if i can run them without needing the wheel spacers but realize i'll probably need them as the stock wheels have ridiculous backspacing. Thanks.

 

you are going to need spacers it will rub, forget spacers change the rims to 4.5" back spacing. you do not put 12.5 inch tires on 7.5" rims . I have 285's with 4.5" back spacing , I am about 2" out.285's are about 11"

 

what he said. just dont listen to the part that says dont put 12.5s on 7.5s. there are hundreds of people on here with this set-up. it's a cheaper way to run bigger tires without having to replace wheels. the right wheel spacers are safe if installed correctly.
