How Measure Wheel Width?
I think I am doing this correct, but just to make sure. Is the advertised wheel width taken on the inside bead surface, bead to bead from the minimum distance between bead or is from outside edge to outside edge?
The reason I ask, these wheels I inherited I have assumed were 15X10 but if I place a tape (tire is mounted) through the wheel and eye ball it to what I think is close to the inside bead minimum radius then it measures about eight. But if I go outside to outside it is 10? These are steel wheels.
