The invention provides a belt tire vulcanization mold, a tire manufacturing method, and a tire. Dirt is not easy to accumulate in a recess disposed on a molding surface. A tire vulcanization mold (1) includes a molding surface (10) for molding a tire during vulcanization molding, and the molding surface (10) includes a first region (11) provided with a plurality of recesses (13) for forming a plurality of protrusions on a tire surface. In the first region (11), two or more recesses (13) are disposed per 1 mm2. Each of the recesses (13) includes a side wall surface (15), a bottom surface (20), and an imaginary recess center axis (13c) extending in the depth direction of the recess (13). In a cross-sectional view of the recess (13) including the recess center axis (13c), the bottom surface (20) includes a bottom protrusion (25) protruding outward in the depth direction. The side wall surface (15) includes an arc surface (16) smoothly connected to the bottom surface (20).
本发明提供带轮胎硫化模具、轮胎的制造方法以及轮胎,污垢不容易堆积在配置于成型面的凹部中。轮胎硫化模具(1)包含在硫化成型时用于使轮胎成型的成型面(10),成型面(10)包含第1区域(11),该第1区域(11)设置有用于在轮胎表面形成多个突起的多个凹部(13)。在第1区域(11)中,每1mm2配置有2个以上的凹部(13)。凹部(13)分别包含侧壁面(15)、底面(20)以及沿凹部(13)的深度方向延伸的假想的凹部中心轴线(13c)。在包含凹部中心轴线(13c)的凹部(13)的剖视图中,底面(20)包含向深度方向的外侧凸出的底部突起(25)。侧壁面(15)包含与底面(20)平滑地相连的圆弧面(16)。
