I need some tires for an FD stock spare wheel and can't find any. I know the size is 135/70/16 but I just can't find any body that sells this size. I have 2 stock spare wheels and want to run these up front when I'm on the track and need a DOT approved front tire to fit on these wheels. The wheel size is 16X4. Does anybody have a lead on who might sell this size tire or any tire that will fit on these wheels for my purpose?
