So, a few weeks ago, I installed my Gibson SS Catback Exhaust. The system is great. Since then, I've swapped my tires for BFG AT KO's (285/75/16) including the spare. The shop that I took it to mounted and balanced all tires and then put the spare back up underneath the X. Well, I was just under there and realized that the spare tire is touching the exhaust, due to the bigger size of the tire. Is this something I should be really worried about?
