Hey guys, I'm not an expert on this but I do know a more than the average person. I need to replace my rear tire but I cannot seem to find a conti OEM Sport contact2 for my rear; they actually discontinued that size. I called up a local tire shop and they have a used pair of Sport Contact2 255/40 19 with 8/32 tread. Will they fit on they Crossfire and if so, how will it affect the stability/ride. Your feedback is much appreciated, thanks.
