A tire mold having an upper half, a lower half, and a hinged segmented center ring mounted on the lower half. The center ring has an upper register between the ring and the upper mold half and a lower register between the center ring and the lower mold half to support the center ring during molding. The lower register is provided by engagement of an inclined surface on the center ring with a lower register surface on a ring flange positioned between the hinge axis of each center ring segment and the inclined surface of the segment. The hinge axis is positioned below a lower split plane between the lower mold half and center ring. The height of the ring flange and the inclination of the lower register surface is selected to provide for swinging movement of the center ring segments with the least interference between the center ring and the tire tread during opening of the mold and to provide the maximum support of the center ring segments during molding of a tire.
