Back in the 1920s, tires were sized by the outside diameter and the section width. That's where the 32 X/ 4 Inches comes from. Around 1928 or so, the nomenclature changed, and tire sizes were based on the nominal rim diameter and the section width. So after the change, a 32 X 4 tire became something like a 21 X 4. I don't know exactly how to cross reference the sizes, but someone at an antique tire vendor, such as Coker Tire, should be able to help you and also supply tires

32-(4 * 2)=24 inch rim. Sometimes metric tubes overlap sizes. Call Coker, they will make sure you get the right size tubes
