ABSTRACT:
Disclosed is a hub replacement device for use in vehicle tire retreading processes. An envelope is sealed against the tire carcass sidewalls to provide an environmental seal of the new tread on the carcass crown during the vulcanization process. Three arcuate rigid plates, each with a pair of ribs, are installed between the carcass beads, for supporting the beads, a predetermined distance apart along a majority of the bead circumference. Integral with each support plate are pairs of opposing toggle clamps with hooked ends. A pair of annular discs are located on each side of the tire for applying a compressive force on the envelope against the carcass sidewalls. The annular discs are each equipped with pairs of anchor loops to which the hooked ends of the toggle clamps are releasably engaged.
