I'm actually a Grand Cherokee guy (NAGCA) my parents have 2 built cherokees, anyways I just have a small question. I have a rear protofab bumper with a tire carrier, It is useless to post this question on nagca because I have the only customer one for the grand so far. The question is about the tire carrier. I have a 33x12.50r15 mounted on 15x10 inch wheels, Is this too big for the bumper or unibody to handle. The tire wiggles about a half inch to an inch max. Just making sure the bumper will handle it? TIA, Jake
