Abstract

A circumferential direction protrusion is provided extending longitudinally mainly along a tire circumferential direction on a side outward in a tire radial direction from a maximum tire width position on at least a first tire side portion of a tire.

First claim

What is claimed is:

1. A pneumatic tire, comprising:
a circumferential direction protrusion extending longitudinally mainly along a tire circumferential direction disposed in a first tire side portion outward in a tire radial direction from a maximum tire width position,
a plurality of radial direction protrusions that extend longitudinally mainly along the tire radial direction is disposed on a second tire side portion,
a radial direction protrusion is not disposed on the first tire side portion, and a circumferential direction protrusion is not disposed on the second tire side portion,
a height that the circumferential direction protrusion protrudes from the first tire side portion satisfies a range of not less than 3 mm and not more than 10 mm, and a width in a lateral direction satisfies a range of not less than 0.5 mm and not more than 5 mm,
a height that the radial direction protrusions protrude from the second tire side portion satisfies a range of not less than 1 mm and not more than 10 mm, a number of the radial direction protrusions disposed in the tire circumferential direction satisfies a range of not less than 10 and not more than 50, and a width in the lateral direction satisfies a range of not less than 0.5 mm and not more than 5 mm,
an indicator provided on the side wall portion and indicating a vehicle inner or outer side such that the first tire side portion is on the vehicle outer side when the tire mounted on a vehicle,
wherein the circumferential direction protrusion is formed divided in the longitudinal direction and coincides with the tire circumferential direction.

2. The pneumatic tire according to claim 1 , wherein divided portions of the circumferential protrusion are arranged in a single row in the tire circumferential direction.

3. The pneumatic tire according to claim 2 , wherein the divided portions are spaced apart from each other.

4. The pneumatic tire according to claim 3 , wherein the divided portions have an arc shape extending parallel to the tire circumferential direction.
