Hello Mike! I should get to this site more often, as this is where the serious folks are! You can install a 130/90-10 tire on the rear of a C3 and it'll rub just a bit on the upper inner fender between the 10:00 and 12:00 positions as viewed from the side. The fix is to fab some brackets to attach to the rear fender bracket mounting points that raise it a couple of inches. I have pictures I'd send you if I had a way to do it; It's not too hard to do with hand tools....Then You can put the 140 tire back there if you want, and still have a rear fender . Gabe
