20140174617 | TIRE - 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. | 06-26-2014 |
20140216617 | TIRE - A tire provided with a plurality of land portions formed by a main groove extending along a tire circumferential direction, wherein the main groove is formed with one intra-groove recessed in a tire inner direction from a surface of the main groove, the intra-groove comprises: a first circumferential groove portion extending along the tire circumferential direction on the first groove wall; a first inclined portion extending from the first groove wall toward the second groove wall on a groove bottom of the main groove; a second circumferential groove portion extending along the tire circumferential direction on the second groove wall; and a second inclined portion extending from the second groove wall toward the first groove wall on the groove bottom of the main groove. | 08-07-2014 |

20100175799 | PNEUMATIC TIRE - The present invention provides a pneumatic tire having: a circumferential groove continuously extending in the tire circumferential direction in a ground contact surface of a tread portion; and a resonator provided in a land portion and constituted of a resonance cell portion opened to a ground contact region at a position distanced from the circumferential groove and a siping portion making the resonance cell portion communicate with the circumferential groove, wherein change in a tread pattern as time lapses can be alleviated without scarifying an effect of reducing pipe resonance sounds. Specifically, an opening width of the siping portion at the ground contact surface of the tread portion is designed to change in the longitudinal direction thereof such that the opening with is relatively narrow on the side of the circumferential groove and relatively wide on the side of the resonance cell portion. | 07-15-2010 |

20140174618 | PNEUMATIC TIRE - A pneumatic tire is provided that has enhanced traction performance. A shoulder main body portion of a first shoulder block is formed with a step portion projecting out in a tire circumferential direction. A height of the step portion is set lower than a height of a tread face of the shoulder main body portion and higher than the height of a lug groove. The step portion extends from a tire equatorial plane side end portion of the shoulder main body portion, beyond a tire width direction ground contact edge, to a tire shoulder portion. | 06-26-2014 |
