An improved tire changing hand tool intended for use with rim mounted tubed or tubeless tires, and adapted for mounting to a suitable base. Apparatus includes a center post; a tubular bracket with rim-engaging flange; a rotatable arm; an extended foot; and an elongated handle adapted for attachment to the arm and foot. The centerpost is secured to a suitable base, the tire rim positioned over the center post in a manner to center and secure the tire rim against the base in preparation for tire repair or replacement. With arm and foot attached to the handle, the arm is slidably engaged about the tubular bracket, the foot is positioned against the tire side in close proximity to the rim circumference, and the handle is forced downward to break the seal between the tire bead and the inner lip of the rim. With arm and foot removed, a flat on the axial end of the handle is used to raise and remove the tire bead from the rim by biasing the handle against the tubular bracket, and rotatably biasing the handle about the rim. A curved extension near the axis end of the handle aids insertion of the tire bead into the rim. An inflation member partially secured to the base in proximity to the adjacent tire side, is inflated to bias the tire away from the base to seat the upper tire bead in relation to the upper tire rim in preparation for inflation of a tubeless tire.
