Apparatus for use in mounting tires on and removing tires from wheel rims comprising a wheel supporting means which comprises three slideable and pivotal arms mounted between two rotatable coaxial plates which on being relatively rotated cause the arms to pivot and slide thereby gripping a wheel. The first plate is rotatably driven and the second plate is continuously engaged by braking means. Resilient means act on the second plate to increase the reaction force between the second plate and the braking means. |
