PNEUMATIC TIRE |
| 摘要 |
A pneumatic tire has a belt layer arranged between a carcass and a tread portion. The belt layer has a first main working belt, a second main working belt arranged at an outer side of the first main working belt in a tire-radial direction, and a reinforcement belt. A cord angle of the second main working belt differs from a cord angle of the first main working belt in a direction with respect to a tire-circumferential direction. A cord angle of the reinforcement belt is not smaller than 6 degrees and not larger than 9 degrees. A width of the reinforcement belt is equal to or wider than 50% of a tire-section width and not wider than either narrower one of the first and second main working belts. |
