Each bend groove 15 has two bent portions 16 and 17 at which the groove is bent. The bent angle θ1 at the first bent portion 16 is greater than the bent angle θ2 at the second bent portion 17.

In a tread portion of a pneumatic tire, a first sipe wall surface of a sipe includes at least two first peak portions and at least one first valley portion at each position of the sipe extension direction, which are bent in a wave-like shape to form surface recesses and protrusions along a sipe depth direction. The first valley portion is sandwiched between the two first peak portions in the sipe depth direction, and extends from one end of the sipe in the extension direction to the other end of the sipe in the extension direction. A recess depth of the first valley portion with respect to the two first peak portions gradually reduces. A position of at least one of the two first peak portions in the sipe depth direction and a position of the first valley portion in the sipe depth direction become gradually closer.

A tire has a tread portion 2 including a first land portion 11. The first land portion 11 includes a first circumferential edge 11a, a second circumferential edge 11b, and a tread surface between the first circumferential edge 11a and the second circumferential edge 11b. On the tread surface, a first inclined groove 21 extending from the second circumferential edge 11b to the first circumferential edge 11a side, a second inclined groove 22 extending from the second circumferential edge 11b to the first circumferential edge 11a side so as to be inclined in a direction opposite to that of the first inclined groove 21, and a triangular block 35 demarcated by the first inclined groove 21 and the second inclined groove 22, are formed. A curved groove 15 curved so as to be convex on the second circumferential edge 11b is formed on the triangular block 35.

On a tread of tire, an inclined width direction groove, a plurality of zigzag sipes, an inclined width direction groove and a plurality of zigzag sipes are repeatedly formed in the tire circumferential direction. The inclined width direction groove communicates with the circumferential direction groove, one end of the sipe portion communicates with the narrow groove portion, and the other end of the sipe portion terminates in the rib-like block without communicating with the circumferential direction groove. The inclined width direction groove communicates with the circumferential direction groove, one end of the sipe portion communicates with the narrow groove portion, and the other end of the sipe portion terminates in the rib-like block without communicating with the circumferential direction groove.

A tire has a tread portion that can include a first tread ground contact end on one side in a tire axial direction, a first shoulder circumferential groove closest to the first tread ground contact end, and a first shoulder land portion demarcated to be disposed outwardly of the first shoulder circumferential groove in the tire axial direction. A plurality of first shoulder grove portions extending from the first shoulder circumferential groove to the first tread ground contact end e1 can be in the first shoulder land portion. A pair of first shoulder groove portions adjacent to each other in a tire circumferential direction can have different angles relative to the tire axial direction. The plurality of first shoulder groove portions can include a plurality of kinds of first shoulder groove portions having different first pitch lengths at a connecting portion to the first shoulder circumferential groove. A maximum value of the first pitch length can be 1.2 to 1.5 times an average of the first pitch lengths.

A tire includes a tread having a shoulder region, a shoulder transverse groove being fixedly set in the shoulder region, and a shoulder block row configured by aligning the shoulder blocks in a tire-circumferential direction, in which the shoulder transverse groove has an angle formed by a groove wall and a vertical line drawn from a groove opening end position to a tread surface of the shoulder block within a range of 10 to 20 degrees, and the groove wall and groove bottom are connected by a concave surface with a radius of curvature of at least 6 mm and no more than 15 mm.

In a pneumatic tire, a groove depth H1 of each of first and second inclined lug grooves over an entire region from an opening portion to a corresponding one of first or second circumferential main grooves to a terminating end portion within a center land portion has a relationship with a maximum groove depth Hg of the corresponding one of the first or second circumferential main grooves represented by 0.80≤H1/Hg≤1.00. Additionally, a maximum groove depth H2 of each of first and second lateral grooves has a relationship with a groove depth H1e at a terminating end portion of the corresponding one of the first and second inclined lug grooves represented by 0.70≤H2/H1e≤0.90.

A tire includes a tread portion including four circumferential grooves between outboard and inboard tread edges, and five land portions divided by the circumferential grooves. The circumferential grooves include an inboard shoulder circumferential groove located nearest to the inboard tread edge in the circumferential grooves. The land portions include an inboard shoulder land portion disposed axially outward of the inboard shoulder circumferential groove and having a ground contact surface with the smallest axial width in the land portions. The inboard shoulder land portion is provided with inboard shoulder lateral grooves and inboard shoulder sipes. The inboard shoulder lateral grooves include inner ends away from the inboard shoulder circumferential groove. The inboard shoulder lateral grooves extend axially outward from the inner ends to a location beyond the inboard tread edge. The inboard shoulder sipes extends from the inboard shoulder circumferential groove to a location beyond the inboard tread edge.

A tire has a tread portion having a second middle land region which is provided with middle lateral grooves and circumferentially divided into middle blocks. Each middle block is provided with two first middle sipes extending from a second shoulder circumferential groove, and one second middle sipe disposed between the two first middle sipes. Each first middle sipe extends in a wavy manner in its depth direction. The second middle sipe extends straight in its depth direction. The second middle sipe extends from the second shoulder circumferential groove and is terminated within the second middle land region.

A pneumatic tire includes a circumferential direction groove extending in a zigzag shape with a first groove part and a second groove part being aligned alternately, a first land part and a second land part. A first lateral groove has a first opening that opens to the first groove part, one groove wall of the first lateral groove is connected to a first land part-side second groove wall demarcating the first land part in the second groove part. A second lateral groove has a second opening that opens to the first groove part and longer than the first opening in the tire circumferential direction, one groove wall of the second lateral groove is connected to a second land part-side second groove wall demarcating the second land part in the second groove part, and the second opening is provided on an extension of the first land part-side second groove wall.
