[Object] A pneumatic tire 2 which is excellent in durability is provided. [Solution] The tire 2 includes a tread 4, wings 6, sidewalls 8, clinch sections 10, beads 12, a carcass 14, support layers 16, a belt 18, and a band 20. The sidewalls 8 include multiple dimples 62. When air flows into the dimples 62, turbulent flow is generated. The turbulent flow allows heat of the tire 2 to be released to the air. The surface shape of each dimple 62 is an ellipse. The length La of the major axis of the ellipse is longer than the length Li of the minor axis of the ellipse. The ratio (La/Li) is greater than or equal to 1.2/1, and is not greater than 5/1. The depth of each dimple 62 is greater than or equal to 0.2 mm, and is not greater than 7 mm. The clinch sections 10 may include the dimples 62. |
