I found it on the internet, don't recall exactly where, but I have a
vague recollection of doing a standard to metric conversion along the
line in the process. I think the tire turned out to be a tight fit on
the hub but just required some persistence. The tubes delivered with,
(tires come in pairs), were unusable because of the stems. A local
tire store was able to set me up with 90 deg bent stems on appropriate
tubes.
