摘要:
The present invention relates to a pneumatic tire 1 in which turbulent-flow generating projections 10 each extending from an inner circumference side to an outer circumference side are provided on a outer circumferential face 3a which is tire surface of tire side portion 3 at intervals in a tire circumferential direction. Each of the turbulent-flow generating projections 10 includes an edge portion 10g when being viewed in a cross-sectional shape taken along a direction perpendicular to an extending direction thereof, and a front wall angle θ formed between a front wall face 10a of each turbulent-flow generating projection 10 and the tire surface (outer circumferential face 3a) is set in the range of 70° to 110°, the front wall face being hit by an airflow.
