A pneumatic tire includes at least four circumferential main grooves that extend in a tire circumferential direction; and at least five land portions defined by the circumferential main grooves. The center land portion and the left and right second land portions each include through lug grooves that are inclined at a predetermined inclination angle with respect to the tire lateral direction and extend through the land portion in the tire lateral direction. The through lug grooves located in the center land portion and the through lug grooves located in the left and right second land portions extend in the tire lateral direction inclined in opposite directions to each other. At least one groove wall of each of the through lug grooves located in the left and right second land portions include a step-shaped bent portion that bends in the tire circumferential direction in a plan view of a tread.

A tire comprises a tread portion 2. The tread portion 2 comprises a plurality of first oblique grooves 10A extending obliquely from a first tread edge Te1 positioned on one side in a tire axial direction toward a tire equator C. Each of the first oblique grooves 10A comprises a main body portion 12 extending from the first tread edge Te1 without reaching the tire equator C and a branch portion 13 branching off from the main body portion 12 and extending to cross the tire equator. The branch portion 13 terminates without being connected with other grooves than the first oblique grooves 10A.

A tyre includes a tread portion including a tyre equator, a tread edge, a tread width which is a distance in a tyre axial direction from the tyre equator to the tread edge, a shoulder land portion including the tread edge. The shoulder land portion is provided with a plurality of first shoulder lateral grooves. Each first shoulder lateral groove includes an inner groove portion extending inwardly in the tyre axial direction of the tread edge and an outer groove portion extending outwardly in the tyre axial direction of the tread edge. Each first shoulder lateral groove, in a tread development view, has a groove area Sb of the outer groove portion extending in a region from the tread edge to an 125% position of the tread width is greater than a groove area Sa of the inner groove portion.

A pneumatic tire comprises at least four main grooves extending in the tire circumferential direction on the tread surface, circumferential land portions and shoulder land portions partitioned and formed by these main grooves, and designation of a mounting direction with respect to a vehicle, wherein a plurality of lug grooves is formed at intervals in the tire circumferential direction in each of the plurality of circumferential land portions, extending in the tire width direction, communicating with the main groove on the vehicle inner side, not communicating with the main groove on the vehicle outer side, and terminating within the circumferential land portion.

A tire has three or more circumferential direction main grooves, a first land portion and a second land portion that are partitioned by the circumferential direction main grooves, first sipes that are provided in the first land portion, and that have a bend portion protruding in the tire circumferential direction, and whose two ends communicate respectively with the circumferential direction main grooves, second sipes that are provided in the second land portion on a virtual extension of the first sipes, and whose two ends communicate respectively with the circumferential direction main grooves, and first terminal grooves that are provided in the first land portion between first sipes, that are positioned on an outer side in a tire width direction of the first land portion and communicate with the circumferential direction main grooves, and that terminate at a position further to the outer side in the tire width direction than a position in the tire width direction of a distal end of the bend portion, wherein angle portions on an acute angle side relative to the tire circumferential direction of the first land portion facing the first sipes are chamfered.

In a pneumatic tire, a land portion includes a chamfered portion formed on an edge portion of the land portion on a ground contact edge side, and a lug groove and a narrow groove disposed correspondingly to the chamfered portion. The chamfered portion is formed on the edge portion on a ground contact edge side, and has a chamfered width that increases toward a circumferential direction in the road contact surface of the land portion. The lug groove terminates in the land portion on one end, and is opened to a central portion of the chamfered portion in a longitudinal direction on the other end. The narrow groove is opened to an edge portion of the land portion on an equatorial plane side on one end, and terminates in the vicinity of a maximum width position of the chamfered portion on the other end.

Provided is a pneumatic tire. An outer side intermediate land portion and outer side shoulder land portion have lug grooves extending in a width direction while curving; one end of the lug grooves in the outer side shoulder land portion reaches a ground contact edge, while the other end terminates in the outer side shoulder land portion; one end of the lug grooves in the outer side intermediate land portion communicates with a shoulder main groove and the other end terminates in the outer side intermediate land portion; an opening end of the lug grooves in the outer side intermediate land portion with respect to the shoulder main groove exists on an extension line of the lug grooves in the outer side shoulder land portion; and a pair of lug grooves adjacent in the outer side intermediate land portion are disposed to not overlap each other in the circumferential direction.

A pneumatic tire includes circumferential main grooves extending in the tire circumferential direction and arranged side by side in the tire width direction and a land portion defined by the circumferential main grooves. The land portion includes notch portions extending in the tire width direction and connected to the circumferential main grooves and shallow groove portions connected to the notch portions, respectively, and terminating in the land portion. The height of the notch portions decreases continuously toward the circumferential main grooves connected thereto.

Disclosed is a pneumatic tire including: in a tread surface of a tread portion, a pair of main grooves (center main groove and shoulder main groove) arranged side by side in a tire lateral direction and extending in a tire circumferential direction; land portions (middle land portion) defined by the main grooves; a plurality of lug grooves arranged side by side in the tire circumferential direction and bent and folded back, each of the lug grooves including one end communicating with the shoulder main groove, the other end terminating within the middle land portion, and a bending point in a middle of a path from one end to the other end; and sipes extending across the lug grooves, at least one side of the sipe with respect to the lug groove being formed in a zigzag shape.
