ok by tire size it means the rubber not the rim. you need to take the measurements off the sidewall. the 3 digit number is the number you need. i'm not sure how you convert it to inches. or check the manufacturers website and see if they have a chart1968 Camaro SS 509 BB M4<br />1970 Mustang Mach 1 351W M4<br />1985 Mustang GT 302 M5<p>Me: Scratch your chin for me.<br />Jepe: $@&% you<p>dstrbdv6: if you live past forty i\'ll start going to church again
