Metric system is based on:
"Width (millimeters)" / "Aspect Ratio (percent)" "R for radial" "Rim Size (inches)"
Diameter (inches) = width / 25.4 * 2 * aspect ratio / 100 + rim size
i.e. for 245/75R16
245 / 25.4 * 2 * 75 / 100 + 16 = 30.47"
Width (inches) = width / 25.4
i.e. for 245/75R16
245 / 25.4 = 9.65"
