A tire changing apparatus is provided in which a lower bead-breaking shoe is pivotally mounted on a lever arm at one distance from the lever fulcrum and in which power is transmitted to the lever arm at a greater distance from the lever arm fulcrum. The bead-breaking shoe is of such a form that the leading edge of the shoe meets the wheel rim with its centerline spaced therefrom and engages the tire bead at substantially the leading edge centerline, thereafter engagement expanding progressively about the tire bead perimeter.
