ABSTRACT:
Articles of manufacture useful in mounting/demounting tires on custom automobile wheels made from magnesium, aluminum and other similar metals or alloys thereof. One article is a wheel hub interface element, a first portion of which is configured to fit over and around a portion of the hub of a custom wheel and a second portion of which is configured to receive the mounting cone of a conventional tire changer apparatus. The interface element permits the wheel to be secured in position in a conventional tire changer for tire mounting/demounting, without damage to the wheel hub. The other article is an improved combination tool for mounting/demounting tires on custom wheels, specifically, seating/breaking a tire bead on/from the wheel rim. The tool includes a base portion, a mounting portion and a demounting portion. The base portion receives a combination tool handle. The demounting portion extends away from the base portion, and is relatively flat and thin with a knob-like element extending across its free end. The mounting portion extends away from the base portion but is curved relative to the base in a generally U-shape, configured to fit around a portion of the wheel rim. The combination tool is made from a material which is sufficiently rigid to withstand the pressure applied to it during tire-changing operations, yet is not abrasive, and hence does not cause cosmetic damage to the custom wheel.
