The Anatomy of a Bicycle Tyre
I picked up an old Norman Ladies’ frame recently and the front wheel/tire was on odd size, 26″ x 1 1/4″.
The tire itself was an old Dunlop Champion and completely shot. I wanted to keep the inner tube as I find old tubes hold air better than the new ones.
I tried to remove the tire with the regular tire irons but found it would not budge. Closer examination revealed a metal wire bead.
I cut the bead with bolt cutters and got it off.
26 x 1 1/4.
Hard to see but says “Inflate Hard”.
I suspect that this was an expensive racing tire.
