Abstract: A pneumatic tire includes, in a tread portion, a main groove extending in a tire circumferential direction, a lateral groove extending in a tire width direction, and a land portion formed by the main groove and the lateral groove. The land portion is formed with a sipe extending in a tire width direction. The sipe has a wave-shaped portion of two cycles or less having a larger depth than both end portions on portion thereof excluding the both end portions.

Abstract: A tread portion of a pneumatic tire is divided into a center region at a center portion in a tire width direction and shoulder regions disposed on both sides of the center region. Each of the center region includes ribs which are formed by a plurality of main grooves extending in a tire circumferential direction. The shoulder region includes: a plurality of inclined grooves which are inclined toward the outside in a tire width direction and toward a direction opposite to a tire rotational direction at the time of advancing a vehicle; and a shoulder block surrounded by the inclined grooves.

Abstract: A pneumatic tire has a first region including a plurality of first zones disposed adjacently to each other in a tire circumferential direction, each first zone being formed in a closed region and extending in a first extending direction; and a second region which is disposed adjacently to the first region in a tire radial direction and includes a plurality of second zones, each second zone being disposed adjacently to each other in a tire circumferential direction, being formed in a closed region and extending in a second extending direction. On an end portion of the first region disposed adjacently to the second region, valley portions are formed by the first zones disposed adjacently to each other in the tire circumferential direction. Each of the second zones has a portion disposed adjacently to the first region and configured to mate with each of the valley portions.

Abstract: A shoulder land portion is constructed by block rows. Shoulder lateral grooves sectionalize the block rows. The shoulder lateral grooves extend along the tire width direction in such a manner as to cut across ground contact ends. A plurality of projections is provided on a wall surface of the shoulder lateral groove. The projections protrude out of the wall surface of the shoulder lateral groove without reaching a center of a groove width of the shoulder lateral groove and are lined up in a length direction of the shoulder lateral groove in an outside area in the tire width direction from the ground contact end. The projection is formed into a triangular shape or a trapezoidal shape in its plan view and is formed into a triangular shape or a trapezoidal shape in its front elevational view.

Abstract: Sipe groups including a plurality of sipes which is opened to a main groove and is arranged at intervals in a tire circumferential direction are formed in both land parts with the main groove being interposed therebetween. The sipe groups are arranged at intervals in the tire circumferential direction, and are shifted in the tire circumferential direction on both sides of the main groove.

Abstract: An installation members 20 is structured detachably by a fitting structure between a groove portion 12 and a projection 21 extending in a tire peripheral direction CD, with respect to a tire side wall surface 10. a structure in which the groove portion 12 and the projection 21 interfere with each other in the tire peripheral direction is provided between the groove portion 12 and the projection 21.

Abstract: A pneumatic tire includes a tread surface which is sectioned into a center area, a mediate area arranged in an outer side of the center area, and a shoulder area arranged in an outer side of the mediate area, wherein inclined grooves are formed spaced apart in a tire circumferential direction, the inclined grooves continuously extending from the mediate area to the shoulder area, in blocks in the mediate area and the shoulder area sectioned by the inclined grooves, an angle of inclination of a side wall on a leading side with respect to a normal direction of the tread surface is greater than an angle of inclination of a side wall on a trailing side with respect to a normal direction of the tread surface, and a plurality of dimples are formed in the side wall on the leading side of the block in the mediate area.
