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.

Hard to see but says “Inflate Hard”.

I suspect that this was an expensive racing tire.

  1. I seem to remember “inflate hard” being something to do with encouraging cyclists to keep their tyres extra hard during the war to conserve rubber.
