fiveoh patrol is right...please don't put glasspacks and or side exhaust on a fox. as far as tire sizing, my take is... take a 275/40-17 as an example. 275 is the tread width in millimeters. 40 is the percentage of the sidewall compared to the width of the tire from sidewall to sidewall (not tread width). (so in the case of our example tire, the side wall width would be 40% of the width from sidewall to sidewall (which is just slightly more than the tread width). of course 17 is the rim size (diameter in inches). don't know what would be good for the look you are going for, but don't stick the rear tire too much from the fender or (i think that looks like crap). to me the widest you can go while still fitting inside the fender well, or just outside looks best.
