PNEUMATIC TIRE |
| 摘要 |
A pneumatic tire comprises a sidewall portion provided in the outer surface with a serrated area defined by radially-extending circumferentially-arranged ridges. The serrated area has circumferentially-arranged groups each including: at least one first ridge being straight over the entire length; and a plurality of second ridges, circumferentially arranged side-by-side, and each provided with an irregular part and otherwise being straight. In each of the ridge groups, the irregular parts of the second ridges are gradually radially shifted so that the irregular parts are arranged along a line inclined with respect to a tire radial direction, and by the irregular parts, an oblique pattern is formed in the ridge group. |

1. A pneumatic tire comprising a sidewall portion provided in the outer surface thereof with a serrated area defined by radially-extending circumferentially-arranged ridges, wherein
the serrated area has circumferentially-arranged groups each including: one first ridge or a plurality of first ridges circumferentially arranged side-by-side, each being straight over the entire length; and a plurality of second ridges, circumferentially arranged side-by-side, and each provided with an irregular part and otherwise being straight, and in each of the ridge groups, the irregular parts of the second ridges are gradually radially shifted so that the irregular parts are arranged along a line inclined with respect to a tire radial direction, and the irregular parts form an oblique pattern in the ridge group. |
