They predate numerical designations but originally were
called 28 inch as they were a lot fatter then. Actual rim
diameter is 630mm.

So the tire was named by major diameter x width and the wheel
by major tire diameter minus twice the minor diameter? That's 
sensible. Provided the cross section is always circular. Is it?

Thanks for writing!
