PROBLEM TO BE SOLVED: To provide an improved tire mold the tread zone and sidewall zone of which can obtain appropriate temperature.SOLUTION: A tire mold 10 includes an upper mold part 11 and a lower mold part 12. The upper mold part 11 and the lower mold part 12 are movable relatively to each other for inserting a tire into the tire mold 10. The upper mold part 11 includes an upper sidewall ring 18, and the lower mold part 12 includes a lower sidewall ring 34. The lower mold part 12 further includes a plurality of tread segments 32 that are connectable to each other so as to form an annular ring for surrounding a tread of a green tire. In addition, the upper and lower sidewall rings 18, 34 include internal cavities 100, 102 which are filled with heat insulation material, respectively. |
