The curing press for a tire blank includes a frame and a plurality of circumferentially distributed segments which are capable of forming a tread for the tire. Each of the segments has at least one opening. For each segment, at least one tie rod is mounted slidably and rotatably in the opening of the segment on the one hand and hinged to the frame on the other hand. The mounting and hinging form the only connections of the tie rod to elements of the press other than the tie rod.

A tire vulcanizing device includes a vulcanization mold and a central part. The vulcanizing mold includes molding parts that defining a curing chamber therebetween. Inside the curing chamber is arranged a heating and ventilation apparatus structured for use with a heat-transfer fluid. The central part is structured to collaborate with the vulcanization mold by providing support to a heat-transfer fluid inlet and establishing communication between the heat-transfer fluid inlet and the curing chamber. The central part includes heating elements that are configured to be brought into operation before the heating and ventilation apparatus is brought into operation to cure a tire using the heat-transfer fluid.
