20140290817 | PNEUMATIC TIRE - A pneumatic tire according to the present invention including a tread surface having at least one circumferential groove extending along a tire circumferential direction and a plurality of widthwise grooves opening to the circumferential groove, the widthwise grooves having a groove width wider than a groove width of the circumferential groove at least in a portion opening to the circumferential groove and, the widthwise grooves extending in a direction inclined with respect to the tire circumferential direction, wherein a recess is formed on a groove wall surface of the circumferential groove opposite to the widthwise groove. | 10-02-2014 |
20140318676 | TIRE - The tire includes a tread portion to come into contact with a road surface. A lateral groove portion extending in a direction intersecting with a tire circumferential direction, and a land portion partitioned by the lateral groove portion are formed in the tread portion. The land portion includes: a ground-contact face to come into contact with the road surface; a side face formed on an outer side in a tread width direction of the land portion; a lateral groove face constituting a groove wall of the lateral groove portion formed on one end in the tire circumferential direction of the land portion; and a tapered face which meets the ground-contact face, the side face, and the lateral groove face in a corner portion formed by the ground-contact face, the side face, and the lateral groove face. | 10-30-2014 |
20150151590 | PNEUMATIC TIRE - A tire is a tire in which circumferential grooves, and lug grooves comprising opening portion in tread end and which extend in the tread width direction from the tread end to the circumferential groove, are formed. Projection parts are provided in the groove bottom of the circumferential grooves. The projection parts extend from one side wall forming a circumferential groove to the other side wall opposite the one side wall. Multiple lug grooves are formed at predetermined intervals in the circumferential direction. In the tread surface view of the tire, given points of intersection as the points at which a circumferential groove extension that passes through a circumferential groove intersects with a lug groove extension that passes through a lug groove, the projection parts are provided between a first point of intersection and a second point of intersection adjacent to the first point of intersection in the circumferential direction. | 06-04-2015 |
