A tire mold having two 'half' molds each including a side wall and a tread molding portion and a center ring having a tread molding portion for molding one third or less of the total width of the tire tread. The center ring is divided into eight sections each hinged to one of the half molds to swing open and outward of interfering portions of the tread pattern, being opened solely by the movement of the tire as it is lifted from the mold. No auxiliary mechanism for driving the sections is used or needed, and the mold is opened and closed in the same manner as the usual two piece tire mold. The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed description.
