So what do the inch designations refer to anyway? 700 mm is about 27 1/2 inches. Does it refer to the OD of the tire? OD of the flange of the rim and the 700mm is the diameter of the bead?
Antique car tires (early 30s and older)are sized by OD. Modern car tires are sized by rim diameter.
Anyone have the knowledge?
