Abstract

A pneumatic tire includes a decorative portion on a tire side portion that is an outer surface of a sidewall portion. The decorative portion includes a plurality of ridges that extend along the tire side portion and are arranged side by side in the tire circumferential direction. The plurality of ridges include a common form of an inclination angle in the tire circumferential direction with respect to the tire radial direction and an interval between a pair of the plurality of ridges adjacent. The plurality of ridges constitute a ridge group. Three or more ridge groups are provided and the plurality of ridges of the different ridge groups are arranged intersecting one another. Accordingly, the pneumatic tire can reduce poor appearance of the sidewall portion.

Claims

1. A pneumatic tire comprising:

a decorative portion disposed on a tire side portion that is an outer surface of a sidewall portion;

the decorative portion comprising a plurality of ridges that extend along the tire side portion, the plurality of ridges being arranged side by side in a tire circumferential direction;

the plurality of ridges comprising a common form of an inclination angle in the tire circumferential direction with respect to a tire radial direction and an interval between a pair of the plurality of ridges adjacent to one another, the plurality of ridges forming a ridge group, and three or more different ridge groups are provided; and

the plurality of ridges of the different ridge groups are arranged intersecting one another.

2. The pneumatic tire according to claim 1, wherein

the plurality of ridges of a same one of the three or more ridge groups have an identical height to one another;

and

the plurality of ridges of the different ridge groups have different heights.

3. The pneumatic tire according to claim 1, wherein at least one of the ridge groups has a plurality of sizes of interval as an interval between a pair of the plurality of ridges adjacent to one another.

4. The pneumatic tire according to claim 3, wherein the ridge group comprising a plurality of sizes of interval as an interval between the pair of the plurality of ridges adjacent to one another has a ridge set formed by the plurality of ridges arranged side by side in a continuous manner in the tire circumferential direction, and a plurality of the ridge sets are arranged side by side in the tire circumferential direction at an interval different from an interval between the plurality of ridges that form the ridge set.

5. The pneumatic tire according to claim 2, wherein at least one of the ridge groups has a plurality of sizes of interval as an interval between a pair of the plurality of ridges adjacent to one another.

6. The pneumatic tire according to claim 5, wherein the ridge group comprising a plurality of sizes of interval as an interval between the pair of the plurality of ridges adjacent to one another has a ridge set formed by the plurality of ridges arranged side by side in a continuous manner in the tire circumferential direction, and a plurality of the ridge sets are arranged side by side in the tire circumferential direction at an interval different from an interval between the plurality of ridges that form the ridge set.
