ABSTRACT:
A machine for breaking the beads on the sidewalls of a giant tire away from the tapered bead seats on a multipiece rim, includes upright backing members against which the giant tire and its rim are positioned and a press-head which is forced against that sidewall of giant tire which is positioned away from the backing members. The force exerted on the press head is derived from a hydraulic cylinder and is transferred to the press head through the center of the rim. The cylinder is detachable from the press head so that a tire can be positioned between the backing members and the press head. The press head rotates and has shoes which bear against the tire sidewall and are movable in the radial direction to accommodate tires of different size. Restraining means are provided for preventing the bead seat ring of the rim from moving toward the backing members under the applied force.
