摘要： A pneumatic tire includes an inclined groove disposed in a first land portion and/or a second land portion which includes at least two bent portions. A sipe is disposed in the first land portion and/or the second land portion so as to intersect the inclined groove at 90°±30°. The sipe includes at least one bent portion.

摘要： Provided is a pneumatic tire. Center blocks provided in a center region of a tread portion are arrayed and form pairs across inclined grooves that are inclined with respect to a tire circumferential direction. Each one of the center blocks extends across a tire equator from one side to the other side of the tire equator. Each one of the center block includes a cut formed of a first wall and a second wall connected in a V-shape in a tread surface. The first wall extends at an angle within ±20° with respect to the tire circumferential direction in the tread surface, and the second wall extends at an angle within ±10° with respect to a tire lateral direction. Each one of wall surface angles of the first wall and the second wall is larger than a wall surface angle of a wall surface provided with the cut.

摘要： Provided is a pneumatic tire. Side blocks are provided at extension positions of shoulder blocks on an inner side in a tire lateral direction, and each of the side block is formed into an L-shape in which a radial portion extending in a tire radial direction and a circumferential portion extending in a tire circumferential direction are coupled in a hook portion. Of the side blocks, first blocks having the circumferential portions oriented to the shoulder block side and second blocks having the radial portions oriented to the shoulder block side form pairs by facing each other so that the circumferential portions of the first blocks and the second blocks overlap with each other. The side block pairs formed of the first blocks and the second blocks are arrayed in the tire circumferential direction.

摘要： Provided is a pneumatic tire. In shoulder regions of a tread portion, as shoulder blocks, inner blocks and outer blocks, which have outer edges in a tire lateral direction at different positions on a tread contact surface, are alternately disposed in a tire circumferential direction. In shoulder grooves disposed between the inner blocks and outer blocks adjacent to each other in the tire circumferential direction, groove bottom protrusions, which extend from a laterally inner side to a laterally outer side in the tire lateral direction along the shoulder grooves over the positions of the outer edges of the inner blocks, are provided. Broad width portions having a relatively broad protrusion width of the groove bottom protrusions are disposed on a laterally outer side in the tire lateral direction with respect to the outer edges of the inner blocks in a front view.

摘要： A pneumatic tire includes a lug grooves extending in a shoulder region of a tread portion in a width direction up to a sidewall portion, a shoulder block and a side block defined by the lug grooves, in which the side block located outward of the shoulder block in the width direction is ridged higher than the shoulder block, at least a part of the lug grooves being each a closed lug groove closed by a ridge portion provided therein, the ridge portion being continuous to the side block located on both sides of the closed lug groove in the circumferential direction, the ridge portion including a first narrow groove with a smaller groove width and a smaller groove depth than the lug groove, extending in the width direction, and at least one end of the first narrow groove penetrating toward the closed lug groove or the sidewall portion.

摘要： A pneumatic tire includes: a circumferential groove in a circumferential direction; and center and shoulder blocks defined by angled inner grooves communicating with the circumferential groove while inclined in one direction with respect to the circumferential direction and by angled outer grooves communicating with the angled inner grooves while inclined in another direction with respect to the circumferential direction, and that includes repetitive elements including the grooves and the blocks, the pitches of the repetitive elements varying in the circumferential direction. The circumferential groove includes widened portions and narrow width portions alternately disposed in the circumferential direction. The angled inner grooves communicate with the widened portions. An inclination angle, formed by an imaginary straight line connecting centers of opening ends of a pair of the angled inner grooves communicating with the widened portion corresponding thereto, with respect to the circumferential direction, decreases as the pitches of the repetitive elements decrease.
