To provide a pneumatic tire capable of suppressing the generation of bare, a tire vulcanizing mold, and a method of manufacturing a pneumatic tire.SOLUTION: A pneumatic tire (1) includes a lateral groove (20) that has a groove bottom surface (21) extending in a direction intersecting a tire circumferential direction, and a protrusion (30) that is provided on the groove bottom surface (21), and extends in a direction in which the groove bottom surface (21) extends. The protrusion (30) includes a body portion (31), and a bulge portion (32) that is provided at an end portion at least on one side in a longitudinal direction of the body portion (31) and is formed so as to increase height from the groove bottom surface (21) from the outside to the inside in the longitudinal direction of the body portion (31). The bulge portion (32) is formed with at least one vent trace (33b, 34b) that is a trace of a vent on a tire vulcanizing mold.SELECTED DRAWING: Figure 4
【課題】ベアの発生を抑制できる空気入りタイヤ、タイヤ加硫金型、及び空気入りタイヤの製造方法を提供する。【解決手段】空気入りタイヤ(1)は、タイヤ周方向と交差する方向に延びる溝底面(21)を有する横溝(20)と、溝底面(21)に設けられ、溝底面(21)が延びる方向に沿って延びる突起(30)とを備える。突起(30)は、本体部(31)と、本体部(31)の長手方向の少なくとも一方側の端部に設けられるとともに、本体部(31)の長手方向の外側から内側に向かって溝底面(21)からの高さが増加するように形成された隆起部(32)とを備える。隆起部(32)は、タイヤ加硫金型におけるベントの痕跡である少なくとも1つのベント痕(33b、34b)が形成されている。【選択図】図4
