A segmented tire mold includes a device for controlling the expansion of the mold segments during the vulcanization of a tire. The expansion control device may be a cable or a ring that is wrapped around the outer circumference of the segmented tire mold and placed into tension in order to retain the mold segments in the proper position while the tire is vulcanized.
