To provide a pneumatic tire capable of improving rut performance. A pneumatic tire according to an embodiment is a tire having a specified rotation direction. A shoulder region of a tread portion is provided with a shoulder block and a raised portion is provided in an outer extension portion of the shoulder block in a tire width direction in relation to a tire ground contact end. The raised portion includes a corner portion which protrudes from an edge portion of the shoulder block on a front side in the rotation direction toward the front side in the rotation direction.

A pneumatic tire includes a tread portion provided with a circumferentially extending zigzag shoulder main groove arranged proximate to a tread edge, and a plurality of shoulder lateral grooves each extending axially outwardly from the shoulder main groove. Each of the shoulder lateral grooves includes a first portion and second portion. The first portion includes a first groove wall and an axially inner end connected to the shoulder main groove. The second portion is arranged axially outward of the first portion and includes a second groove wall. The second portion has a groove width and a groove depth greater than those of the first portion. The first groove wall of the first portion and the second groove wall of the second portion are smoothly continued.

A pneumatic tire is provided with four or more circumferential main grooves extending in a tire circumferential direction and five or more land portions defined by the circumferential main grooves. Additionally, second land portions are each provided with first through lug grooves and second through lug grooves that extend through the second land portion in a tire lateral direction and are adjacently arranged in the tire circumferential direction. Crossing angles of the first through lug grooves and the second through lug grooves with respect to the outermost circumferential main grooves are mutually different.

A pneumatic tire includes a tread portion provided with at least one circumferentially extending main groove, and at least one lateral groove extending from the main groove. The at least one lateral groove comprises a bottom, and at least one stepwise groove wall that includes at least one level part, wherein the number of level part is not more than three. In a cross-sectional view of the lateral groove, a depth Da from a ground contacting surface of the tread portion to a radially innermost level part is in a range of from 50% to 80% a maximum groove depth D4 of the lateral groove, and a width Wa from the radially innermost level part to a groove edge of the stepwise groove wall measured along in a groove width direction is in a range of from 50% to 150% the depth Da.

An off-road tread profile with radially elevated profile elements, which are separated by circumferential channels, and with transversely running channels which open into circumferential channels, wherein the circumferential channels are formed, along their extent over the circumference of the tire, with a varied axial inclination, wherein, in the channel base of a circumferential channel, elevated stone deflectors are formed so as to be free from contact with the channel walls, which stone deflectors are formed from a cylindrical or frustoconical central body with maximum diameter D, the cylinder or cone axis of which is oriented in the radial direction, and from in each case one web-like body situated in front of the body in the extent direction of the circumferential channel and one web-like body situated behind, wherein the two web-like bodies are each formed so as to extend from the shell surface of the central body so as to be oriented parallel to the extent direction of the circumferential channel and point radially away from the central body and with a maximum width b, where (0.5 D)≥b≥1 mm, wherein central bodies are positioned in each case exclusively in circumferential extent regions of opening-in points of at least one transversely running channel into the circumferential channel.

Provided is a pneumatic tire. A profile line (PL1) of a center land portion (X) protrudes further outward in the tire radial direction than a standard profile line (PL0). Profile lines (PL2, PL3) of sub-center land portions (Y1, Y2) and shoulder land portions (Z1, Z2) defined outward of center main grooves (14a, 14b) in the tire width direction protrude outward in the tire radial direction further than the standard profile line (PL0). The shoulder land portions (Z1, Z2) are defined further outward than the sub-center land portions (Y1, Y2). Further, the profile lines (PL2, PL3) of the sub-center land portions (Y1, Y2) and the shoulder land portions (Z1, Z2) each include an outermost point (A2, A4) of the corresponding center main groove (14a, 14b) in the tire width direction and both end points (A5, A6, A7, A8) of the corresponding shoulder main groove (14c, 14d) in the tire width direction.

In a tire, plural outer side cutouts, which respectively correspond to block land portions and extend toward tire width direction outer sides and end midway along outer side land portions, are formed so as to be spaced apart in a tire circumferential direction in tire width direction inner-side side walls, which are exposed to central circumferential grooves, of the outer side land portions that are provided further toward tire width direction outer sides than the two central circumferential grooves respectively. Further, at least portions of tire width direction inner side openings of the outer side cutouts are positioned between maximum position A, at which a tire width direction distance of a corresponding block land portion is a maximum, and an intermediate point B of two vertices that are adjacent at a tire width direction outer-side side wall of the block land portion.

A tyre 1 for a motorcycle comprises a tread portion 2 and a pair of sidewall portions 3 connected with both ends of the tread portion 2 and extending inwardly in a tyre radial direction. A connecting portion 9 of the tread portion 2 and at least one of the pair of the sidewall portions 3 is provided with a plurality of protruding portions 10 each protruding outwardly in a tyre axial direction. The plurality of the protruding portions 10 is arranged in a tyre circumferential direction with a space 11 between each other.

A pneumatic tire includes first and second main grooves, and first sipes and auxiliary grooves on second land portions between the first and second main grooves, the auxiliary grooves opening to the second main grooves and terminating in the second land portions. The auxiliary grooves bend at a bend point and include a first portion extending from an opening end to the bend point, and a second portion extending from the bend point to a terminating end. A groove width of the first portion gradually reduces from the opening end to the bend point. Second sipes have an end that opens to each of the second main grooves and another end that opens to each of the terminating ends. Third sipes have an end that opens to the first main grooves and another end that opens to the first portions. The sipes are parallel to each other.

A pneumatic tire comprises a tread portion 2 provided with shoulder axial grooves 10 extending from a shoulder main groove 3 to a tread edge Te while inclining to a first-side in the tire circumferential direction. The shoulder axial groove 10 has a first-side groove edge, a second-side groove edge, a first-side groove-sidewall 14 extending radially inward from the first-side groove edge 12, and a second-side groove-sidewall 15 extending radially inward from the second-side groove edge 13. The shoulder axial groove 10 has a part where the inclination angle β of the first-side groove-sidewall 14 with respect to a normal line passing through the first-side groove edge 12 perpendicularly to the tread surface 2s is more than the inclination angle α of the second-side groove-sidewall 15 with respect to a normal line passing through the second-side groove edge 13 perpendicularly to the tread surface 2s.
