PNEUMATIC TIRE

A pneumatic tire suppresses defects of a sidewall outer surface. The pneumatic tire includes a pair of sidewall portions extending inward in a tire radial direction from both edges of a tread portion. At least one of the sidewall portions (3) is provided with a vent line (11) and a recessed portion (12) adjacent to each other in the tire radial direction. The vent line (11) protrudes from a sidewall outer surface (3s) and extends in a tire circumferential direction. The recessed portion (12) is recessed from the sidewall outer surface (3s) at a first depth Dc. A serration pattern (15), in which a plurality of ridges (16) extending in the tire radial direction are arranged in the tire circumferential direction, is formed in the recessed portion (12). Each of heights (Hc) of the ridges (16) is smaller than the first depth (Dc). 一种充气轮胎，抑制胎侧外表面的缺陷的发生。该充气轮胎具有从胎面部的两端向轮胎径向内侧延伸的一对胎侧部。在胎侧部(3)的至少一方，在轮胎径向上相邻地形成有排气线(11)以及凹部(12)，该排气线(11)从胎侧外表面(3s)突出并沿轮胎周向延伸，该凹部(12)从胎侧外表面(3s)以第一深度Dc凹陷。在凹部(12)内形成沿轮胎周向排列有沿轮胎径向延伸的多个脊部(16)而成的锯
