To provide a tire mold capable of preventing occurrence of vulcanization failure in a wide range in a tire radial direction, and to provide a pneumatic tire prepared by using the tire mold.SOLUTION: A tire mold having a side formation face for forming the side wall of a pneumatic tire comprises: a side formation face forming a corresponding smooth face on an area corresponding to the area inside a tire maximum width position of the side wall in a tire radial direction in order to form the smooth face on the above area; a first continuous groove provided in the corresponding area and extending in a tire mold radial direction corresponding to the tire radial direction; and an air vent path provided inside the tire mold for venting air from the side formation face when vulcanizing the tire using the mold. The groove depth of the first continuous groove undulates along the radial direction of the tire mold, and the air vent path is open on the groove bottom of a deep groove part in which a groove becomes deep. The pneumatic tire is prepared by using the above mold.SELECTED DRAWING: Figure 4

    【課題】タイヤ径方向の広い範囲において加硫故障の発生を抑えるこができるタイヤ金型及び空気入りタイヤを提供する。【解決手段】空気入りタイヤのサイドウォールを形成するサイド形成面を有するタイヤ金型は、空気入りタイヤのサイドウォールのタイヤ最大幅位置よりもタイヤ径方向内側の領域に平滑面を形成するために、前記領域に対応する対応領域に対応平滑面を形成するサイド形成面と、前記対応領域に設けられ、タイヤ径方向に対応するタイヤ金型の径方向に延びる第1連続溝と、前記タイヤ金型の内部に設けられ、前記タイヤ金型を用いたタイヤの加硫の際に前期サイド形成面から気体を抜くための気体抜き通路と、を有する。前記第1連続溝の溝深さは、タイヤ金型の径方向に沿って波打っており、前記溝深さが深くなった深溝部の溝底に、前記気体抜き通路が開口している。このタイヤ金型を用いて空気入りタイヤを作製する。【選択図】図4
