PNEUMATIC TIRE AND METHOD OF PRODUCING THE SAME |
| 摘要 |
Disclosed is a pneumatic tire that includes a tread having a pattern asymmetrical about the tire equatorial plane, and that may reduce cavity resonance and has good steering stability. A pneumatic tire includes a tread portion having a pair of tread halves, the tread halves extending between the tire equatorial plane and respective outer ends in the tire width direction of the tread portion, respectively, and having different negative ratios. The tread portion has short fibers fixed to at least a portion of a tire inner peripheral surface of the tread portion, and one of the tread halves with a higher negative ratio has a higher short-fiber fixation area ratio than that of the other tread half. |

1. A pneumatic tire comprising a tread portion, the tread portion having an asymmetrical tread pattern and a pair of tread halves, the tread halves extending between a tire equatorial plane and respective outer ends in the tire width direction of the tread portion, respectively, and having different negative ratios,
wherein the tread portion has short fibers fixed to at least a portion of a tire inner peripheral surface of the tread portion, and one of the tread halves with a higher negative ratio has a higher short-fiber fixation area ratio than that of the other tread half. |
