The block includes a first sipe and a second sipe extending obliquely toward opposite sides in the tire width direction.

Abstract: A rib-like land section partitioned by main grooves, a plurality of sub-grooves provided in the rib-like land section at intervals in the tire circumferential direction and a groove hole provided between the sub-grooves adjacent to each other and extending in the tire circumferential direction are provided in a tread section. The sub-groove includes a lateral groove portion, in which one end opens to the main groove and the other end terminates inside the rib-like land section, and a longitudinal groove portion extending from the other end of the lateral groove portion to one side in the tire circumferential direction and terminating inside the rib-like land section. The groove hole is formed so that a groove depth at one end part close to a terminal end of the longitudinal groove portion becomes shallower than a groove depth at the other end part far from the terminal end.

Abstract: A pneumatic tire comprises at least one block partitioned by a groove, the at least one block comprises a plurality of corners including a first corner, the at least one block comprises a first corner recess at which a portion toward the exterior in a tire radial direction at the first corner is recessed relative to a reference surface of the groove, and a first corner projection that is arranged toward the interior in the tire radial direction from the first corner recess and that protrudes toward the exterior of the at least one block, and the first corner projection protrudes from the reference surface of the groove.

Abstract: A tire has a lug that forms a contact patch surface, and a recessed region that extends along a prescribed direction and that is recessed relative to the contact patch surface. The recessed region has a first vertical face that that forms a first edge between the first vertical face and the contact patch surface, and a planar base that extends in a width direction of the recessed region which is perpendicular to the prescribed direction. The planar base has at least two planar regions having mutually different heights and arrayed along the prescribed direction. The recessed region further has a second vertical face that connects the two planar regions and that forms a third edge between the second vertical face and a higher one of the planar regions. The third edge is inclined with respect to both a tire width direction and a tire circumferential direction.

Abstract: A tire has a lug, a plurality of first recessed regions that extend from a first major groove, and a plurality of second recessed regions that extend from a second major groove. A central region of the lug protrudes relative to either end of the lug. The plurality of first and second recessed regions are arranged in alternating fashion along a tire circumferential direction. The respective recessed regions each has a planar base that extends in a width direction of the each recessed region. The planar base is horizontal, or is inclined in such fashion that a height thereof increases so as to extend further toward an exterior in a tire radial direction as one proceeds toward a center of the each recessed region. Width of the planar base increases as one proceeds from the center in the width direction of the lug to an end of the lug.

Abstract: A wheel resonator, which is provided by integrating a first member having a first welding surface with a second member having a second welding surface and includes a volume chamber and a communicating tube. The volume chamber has a flat shape and is configured to extend along an outer surface of a vehicle wheel when the wheel resonator is attached to the vehicle wheel. The first welding surface and the second welding surface are welded to each other, and are provided on a single welding plane. The welding plane extends in a circumferential direction and a width direction of the vehicle wheel when the wheel resonator is attached to the vehicle wheel, is a plane on which the volume chamber is divided into two volume portions, and is a plane on which the communicating tube is divided into two communication portions. The communicating tube extends along the welding plane.

Abstract: A pneumatic tire in which a mounting orientation to a vehicle is designated, includes: the at least four land portions include an outside shoulder land portion, an outside quarter land portion, an inside shoulder land portion and an inside quarter land portion. A total ground contact area of the outside shoulder land portion and the outside quarter land portion is larger than a total ground contact area of the inside quarter land portion and the inside shoulder land portion. The outside quarter land portion has a first circumferential sipe extending in a tire circumferential direction. On the first circumferential sipe, a chamfered first inclined surface portion extending in the tire circumferential direction is provided between a vehicle outside inner wall of the first circumferential sipe and s surface of the outside quarter land portion.

Abstract: A pneumatic tire includes the plurality of sipes, when, with regard to each sipe in which the shoulder-side end portion is located closest to a center side among the plurality of sipes, a position of the shoulder-side end portion of the sipe in the tire width direction is taken as a first reference position, and with regard to each sipe in which the center-side end portion is located closest to a shoulder side among the plurality of sipes, a position of the center-side end portion of the sipe in the tire width direction is taken as a second reference position, the plurality of sipes are arranged at regular intervals in the tire circumferential direction, and at other of the first reference position and the second reference position, the plurality of sipes are arranged at irregular intervals in the tire circumferential direction.
