I have had 31X10.50s on my 2011 since it was pretty new and never had any rubbing issues...that is until I recently got a brand new set of BFG KO2s and the only time they rub, is when I'm backing up with it cranked all the way to the left, and the RF tire rubs on a rubber flap on the inner front part of the wheelwell. I need to see if I can pull it away from the tire with a ziptie or maybe just get rid of it all together.
