<p>An accessory tool for use on a tire changing machine when operating on custom alloy wheels is disclosed which clamps onto the tongue portion of the usual tire changer rotatably driven center post which is normally used to rotationally drive a slotted tire tool. The accessory tool has the capability of positioning a tire mount/demount head radially and axially relative to the wheel rim and of securely clamping the mount/demount head in such selected position. Moreover, the clamping action for positioning the mount/demount head automatically lifts the head away from the rim surface to assure no contact between the head and the edge of the wheel rim when the accessory tool is rotated by rotation of the tire machine center post to mount or demount a tire bead over the edge of the rim.</p> |
