is it a 2011 or 07-2010? 2011 changed bolt pattern. Should easily be able to run a 33'' tall tyer 305-325 wide he could possibly fit a 35 tall with correct back spacing but bumper will have to be trimmed and will still rub a bit on the sway bar. Now im not 100% sure on this but there is more clearance than a 01-07 and ive seen lowered on 35's with H2 wheels
