A tool for use in conjunction with a center-post tire changing machine for mounting and demounting pneumatic tires from wheel rims includes an elongated shaft member having first and second ends wherein a portion of the elongated shaft member defines a main plane of the tool. A tire mounting portion at the first end includes a rounded first face forming a bead contact area, a flat second face forming a rim contact area, and a retaining knob protruding from the flat second face, the tire mounting portion being angularly offset from the main plane vertically by a first bend and horizontally by a second bend. A tire demounting portion at the second end includes a rounded first face forming a bead contact area, a flat second face forming a rim contact area, and a retaining knob protruding from the flat second face. The tire demounting portion is angularly offset both horizontally and vertically from the main plane by a third bend.
