Clincher Tires

The Term Clincher tire is the American term for beaded edge tyres. There is no difference between Beaded edge tyres and clincher tires. Beaded edge tyres need a minimum tyre pressure of 60psi to push the beads into the clincher of the rim and keep the clincher tire in place. The most common cause of a beaded edge vintage tyre failure is lack of pressure allowing the tyre to detach itself. Beaded edge tyres (clincher tyres) can only be used with a beaded edge or (clincher) wheel rim.
