[Object] To provide a pneumatic tire 82 which is excellent in durability. [Solution] A tire 2 includes a tread 4, wings 6, sidewalls 8, clinch portions 10, beads 12, a carcass 14, support layers 16, a belt 18, a band 20, an inner liner 22, and chafers 24. Dimples 62 are formed on the sidewall 8 that is at an inner side in a width direction of a vehicle when the tire is mounted on the vehicle. No dimples 62 are formed on the sidewall 8 that is at an outer side in the width direction of the vehicle when the tire is mounted on the vehicle. The ratio (Ha/Hb) of a height Ha at an outer end 52, in a radial direction, of the bead 12 from a base line BL relative to a height Hb at a maximum width position P max from the base line is equal to or greater than 0.80 but equal to or less than 1.10.
