Abstract
To provide a pneumatic tire having a tire side portion with an enhanced durability according to the present invention, a run flat tire (1) has a turbulent generating concavo-convex part (5) composed of grooves and ribs and extending along at least part of a tire side portion, and a pattern is set to the turbulent generating concavo-convex part (5), in which for the turbulent generating concavo-convex part (5), letting h be a height, p be a pitch, and w be a width, a relationship is met such that 1.0≦p/h≦50.0, and 1.0≦(p−w)/w≦100.0.

A pneumatic tire wherein
- a tire side portion comprises a concave-convex part extending along at least part of an outer side of the tire side portion;
- the concavo-convex part is composed of grooves and ribs,
- for the ribs, letting h be a height, p be a pitch, and w be a width, a relationship is met such that 1.0≦p/h≦50.0, and 5≦(p−w)/w≦100,
- wherein for the ribs, the height (h) is such that 0.5 mm≦h≦7 mm, and the width (w) is such that 0.3 mm≦w≦4 mm.
