To suppress a generation of a bare fault without being constrained by design such as an emblem.SOLUTION: A contour shape K of a sidewall molding surface 2s of a vulcanizing mold 1 changes in circumferential direction of a tire. The contour shape K has an uneven surface repeating in the tire circumferential direction alternately a valley portion 10 in which a contour line J in the tire meridional section is a first outline Ja passing through an outermost side in a tire axial direction, and a top portion 11 in which the contour line J is a second contour line Jb passing an innermost side in the tire axial direction.SELECTED DRAWING: Figure 1
【課題】 標章等のデザイン上の制約を受けることなくベアの発生を抑制する。【解決手段】 加硫金型1のサイドウォール成形面2sは、その輪郭形状Kがタイヤ周方向に変化する。輪郭形状Kは、タイヤ子午断面における輪郭線Jのうちで、タイヤ軸方向最外側を通る第1の輪郭線Jaを有する谷部10と、タイヤ軸方向最内側を通る第2の輪郭線Jbを有する頂部11とがタイヤ周方向に交互に繰り返される凹凸面状をなす。【選択図】図1
