I had 31X10.5-15 BFGoodrich Rugged Trail T/A on my old XLT.I had some rubbing issues up front when making hard turns. I know with the Edge you can crank teh torsion bars and get a little more lift up front for more clearance but they still rub when turning. Plus I think with a factory rim you can't really go over a 10.5" tire.
