ABSTRACT:
A vulcanizing mold for pneumatic vehicle tires with upper and lower mold segments distributed over the circumference of the mold, for molding the tread surface of the respective tire to be molded, while the mold segments cooperate with rings for selectively moving the segments toward the tire tread surface to be molded. The mold furthermore comprises rings which mold the tire side walls and are provided with seating surfaces for receiving and guiding the tire beads. The rings for moving the segments toward the circumferential tire surface consist of two rigid pressure rings which are movably guided in axial direction of the tire to be molded and by means of pressure exerted from the outside of the mold upon the pressure rings are movable toward each other for moving the segment sections together and toward the circumferential area of the tire.
