Somtimes it says

I have started to compile a list of all tire
sizes I come across, and I'm sure I'm the first
dude ever to get this idea. Anyway here is the
result so far:

----------------------------------------------------------------------

642 700 original wagon wheel OD
635 700B B = 2nd revision
