ABSTRACT:
Apparatus usable with a tire mold for curing large off-the-road tubeless tires having varying bead-to-bead spacing. The apparatus includes a lower barrel which supports a vertically moveable adjusting and locking ring on its upper portion and a single floating sealing ring telescopically slideably carried by the lower barrel. The lower barrel and sealing ring are formed with opposed sealing rims. A tire to be cured is interposed between the sealing rims and is then inflated so as to move the floating sealing ring upwardly and form a seal between the sealing rims solely by the resistance of the beads. The tire is then deflated and the assembly positioned in a tire curing mold. Thereafter, the tire is again inflated and the curing operation takes place.
