35's
U should easily be able to clear those. Bshipe22 has just a 3 inch level and clears 315/70/17. With a 2.5 inch level and 3 inch body u should clear without any rub depending on offset/backspacing of your wheels. I just put 315/70/17 on my 4wd with just a 2 inch level and they don't rub at all. Your truck would have more clearance than mine with the body lift.
