TIRE

摘要

A tyre wherein a first bulge part and a second bulge part are formed in a circumferential direction groove. The first bulge part has a narrow-tip shape such that, in the tyre tread plan view, the size in the tread width direction diminishes along a first direction in the tyre circumferential direction. The second bulge part has a narrow-tip shape such that, in the tyre tread plan view, the size in the tread width direction diminishes along a second direction opposite to the first direction in the tyre circumferential direction. A plurality of first bulge parts and second bulge parts are provided at predetermined intervals in the tyre circumferential direction. A groove part which extends in the tyre circumferential direction is provided between the first bulge part and the second bulge part which opposes the first bulge part in the tread width direction.

主权项

1. A tire comprising: a circumferential groove extending in a tire circumferential direction; and a land portion that is adjacent to the circumferential groove and that extends in the tire circumferential direction, wherein
the circumferential groove is formed with:
a first swelling portion that swells from one lateral wall of the circumferential groove toward a center in a widthwise direction of the circumferential groove; anda second swelling portion that swells from the other lateral wall of the circumferential groove toward the center in the widthwise direction of the circumferential groove, the first swelling portion has, in a tread surface view of the tire, a tapered shape in which a size in the tread widthwise direction is narrower as it goes in a first direction in the tire circumferential direction, the second swelling portion has, in the tread surface view of the tire, a tapered shape in which a size in the tread widthwise direction is narrower as it goes in a second direction that is opposite to the first direction in the tire circumferential direction, the first swelling portion and the second swelling portion are formed in plural with a predetermined interval in the tire circumferential direction, and a groove extending in the tire circumferential direction is formed between the first swelling portion and the second swelling portion opposite to the first swelling portion in the tread widthwise direction.
