Problem is I've got 3 near perfect 205's with 6mm left on them. The 4th unfortunately took a bullet in the sidewall. Paul, do you know whether we can put your 225's on the back and leave 2 good 205's on the front? Any ideas what, if any, detrimental effect that might have on the handling? Many thanks!
