Provided is a pneumatic tire including at least a turbulent flow generation projection configured to generate a turbulent flow, the turbulent flow generation projection being arranged in a range from a maximum tire width position to an outside bead position, the maximum tire width position being a position on a tire surface with maximum tire width, and the outside bead position being a position on an outside of a bead portion in a tire radial direction, the bead portion configured to be in contact with a rim flange. The turbulent flow generation projection includes a radial projection extending along the tire radial direction, and a circumferential projection extending in an approximately circular arc shape along a tire circumferential direction. |

1. A pneumatic tire comprising at least a turbulent flow generation projection configured to generate a turbulent flow, the turbulent flow generation projection being arranged in a range from a maximum tire width position to an outside bead position, the maximum tire width position being a position on a tire surface with maximum tire width, and the outside bead position being a position on an outside of a bead portion in a tire radial direction, the bead portion configured to be in contact with a rim flange,
wherein the turbulent flow generation projection includes a radial projection extending along the tire radial direction, and a circumferential projection extending in an approximately circular arc shape along a tire circumferential direction, wherein the radial projection and the circumferential projection are separately provided, wherein a projection height (h) is set to 8 mm to 20 mm, wherein a relationship of 1.0≦h/w≦10.0 is satisfied where “h” is the projection height from the tire surface to a most protruded position of the turbulent flow generation projection, and “w” is a width of a lower side of a cross section approximately perpendicular to an extending direction of the turbulent flow generation projection, and wherein the pneumatic tire is a heavy-duty tire.
