Crossply vintage tyres can be marked in couple of ways, a single measurement like 450x18 or a couple of measurements like 475/500x18. Crossply vintage tyre sizes are given as the height and width of the section of the tyre(450"), plus the diameter of the tyre(18").
Example: 450x18 is 4.5" inches overall width and height of one section of the tyre. 4.5 x 2 = 9 then add the rim diameter (18 inch rim diameter) to the section width 18 + 9 = 27.00 overall diameter.
Crossply vintage tyres do not conform to strict regulations like radial tyres do, so this measuremet is not always 100% accurate and can change from manufactor to manufactor.
