Abstract
A tire changer having a vertical wheel hold down shaft rotatably mounted in a base cabinet and extending upward to a wheel mounting end portion above the cabinet. A collar attached to the hold down shaft beneath its mounting end portion and having a frusto-conical section extending upward to a backing flange centered about the hold down shaft. A locking pin which fits into a wheel lug hole extends upward from the flange. An upwardly extending biased centering cone slidably fitted around the hold down shaft. A bead breaker arm pivotally attached to an outside wall of the cabinet to pivot in a horizontal plane. A pneumatic cylinder is provided which is linked to both the hold down shaft and the bead breaker arm to actuate both, thus providing one pneumatic means for two different functions.
