[Object] To provide a pneumatic tire which is excellent in durability. [Solution] A tire has a large number of dimples 62 on sidewalls thereof. The contour of each dimple 62 is a circle. Each dimple 62 has a slope surface 66 and a bottom surface 68. The dimple 62 has a small projection 70. The small projection 70 is formed on the slope surface 66. The small projection 70 is annular. A cross-sectional shape of the small projection 70 is substantially a rectangle. The small projection 70 is arranged so as to be concentric with the contour of the dimple 62. The surface area of the slope surface 66 having the small projection 70 is larger than the surface area of the slope surface when it is postulated that the small projection 70 does not exist thereon. Preferably, the height of the small projection is equal to or greater than 0.25 mm but equal to or less than 1.0 mm, and the width of the small projection is equal to or greater than 0.25 mm but equal to or less than 1.0 mm. |
