The present invention relates to a tire mold comprising an upper mold portion (11) and a lower mold portion (12), wherein the upper mold portion (11) and the lower mold portion (12) are movable relative to one another for insertion of a tire into the mold (10). The upper mold portion (11) includes an upper sidewall ring (18a, 18b) and an actuating ring (24) having an inner frustroconical surface (25). The lower mold portion (12) includes a plurality of segments (32) each having an upper frustroconical surface (31) and a lower frustroconical surface (28). The lower frustroconical surfaces (28) of the plurality of segments (32) are slidable against an inner frustoconical surface (53) of a bottom mold ring (52). The mold further comprises a lifting plate (50), a lower sidewall ring (34, 34b), and a lifting ring (38) positioned between the bottom mold ring (52) and the lower sidewall ring (34a, 34b). The lifting ring (38), the segments (32) and the lower sidewall ring (34a, 34b) are positioned on the lifting plate (50) for axial movement, and wherein the lifting ring (38) has a first end (2) slidable within a slot (3) of the bottom mold ring (52) and an axially outer surface (39) for engagement with the axially inner surface (47) of a segment (32).
