To effectively suppress occurrence of poor molding at a boundary between a sector and a side plate.SOLUTION: A pneumatic tire T, which is formed by a tire vulcanization mold 100 that comprises a sector 103 which forms at least a portion of a tread 3 and a side plate 102 that contacts the sector 103 to form at least a portion of a side wall 2, comprises an annular protrusion 43 extending in a tire circumferential direction CD formed at a boundary between the sector 103 and the side plate 102, and a recessed part 40 formed closer to outside in a tire radial direction RD than the annular protrusion 43, which sets a distance in the tire radial direction RD from an apex 43a of the annular protrusion 43 to an inside end in the tire radial direction RD of the recessed part 40 to 4.0 mm or more and 4.9 mm or less.SELECTED DRAWING: Figure 3

    【課題】セクタとサイドプレートとの境界部分での成型不良の発生を効果的に抑える。【解決手段】トレッド3の少なくとも一部を形成するセクタ103と、セクタ103に当接してサイドウォール2の少なくとも一部を形成するサイドプレート102と、を有するタイヤ加硫金型100で形成された空気入りタイヤTにおいて、セクタ103とサイドプレート102との境界に形成されたタイヤ周方向CDに連続する環状突起43と、環状突起43よりタイヤ径方向RD外側に設けられた凹所40とを備え、環状突起43の頂点43aから凹所40のタイヤ径方向RD内側端までのタイヤ径方向RDにおける距離を4.0mm以上4.9mm以下に設定する。【選択図】 図3
