PROBLEM TO BE SOLVED: To provide a tire mold in which a surface pressure to be exerted on the end face of an inner segment is limited at the time of mold clamping and change of the surface pressure due to repeated use can be coped easily.SOLUTION: A sector 5 constituting a circular tread mold part includes: an inner segment 6 to be contacted with a tread surface; and a back segment 7 in which the inner segment 6 is mounted on the inner peripheral surface. A spacer 8 is interposed between end faces 70 of two adjacent back segments 7 in a peripheral direction. The spacer 8 is constituted so as to be freely attached to/detached from the end faces 70 of the back segments 7 and is projected into the peripheral direction from one end face 70 thereof. At the time of mold clamping, namely, when adjacent sectors 5 of heated states at the time of vulcanization molding contact continuously with each other in the peripheral direction, a space 20 is formed by the spacer 8 between the end faces 70 of two adjacent back segments 7 in the peripheral direction, and end faces 60 of two adjacent inner segments 6 in the peripheral direction contact each other. |
