A first lateral groove and a second lateral groove are formed in a pneumatic tire. A first inclined portion is formed on one side of the first lateral groove in the tire circumferential direction, and a second inclined portion is formed on the other side of the second lateral groove in the tire circumferential direction. The first inclined portion is inclined from tire radial direction outside to tire radial direction inside by chamfering the end of one side circumferential block in the tire circumferential direction. The second inclined portion is inclined from tire radial direction outside to tire radial direction inside by chamfering the end of the other side circumferential block in the tire circumferential direction. The first inclined portion crosses the circumferential block and communicates with the circumferential groove. One end portion of the second inclined portion in the tire width direction terminates in the circumferential direction block.

A tire includes a tread portion including a pair of shoulder main grooves and a crown region defined between the pair of the shoulder main grooves. The crown region includes a plurality of crown blocks. A ground contacting surface of at least one of the crown blocks is provided with a first sipe, a second sipe, and a third sipe. The first sipe, the second sipe, and the third sipe are connected with each other at one intersection.

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.

Center land portions of a tire each include a circumferential narrow groove extending in a tire circumferential direction, and a first lateral groove opening to one edge portion of each of the center land portions at one end and connecting to the circumferential narrow groove at the other end, and a second lateral groove opening to the other edge portion of the center land portion at one end and connecting to the circumferential narrow groove at the other end. Further, the circumferential narrow groove has a zigzag shape formed by repeatedly connecting a first long portion, a first short portion, a second long portion, and a second short portion. Furthermore, the first lateral groove connects to the first long portion of the circumferential narrow groove having the zigzag shape, and the second lateral groove connects to the second long portion of the circumferential narrow groove having the zigzag shape.

Provided is a pneumatic tire including: a plurality of main grooves each having a zigzag shape and extending in a tire circumferential direction; and a land portion defined by the main grooves adjacent to each other and having a rib structure that is continuous with the tire circumferential direction. The land portion includes first and second lug grooves having a semi-closed structure. A maximum length L21 of the first lug groove in a tire width direction has the relationship 1.30≤L21/L22≤2.30 with respect to a maximum length L22 of the second lug groove.

Provided is a pneumatic tire including a plurality of main grooves extending in a tire circumferential direction and land portions defined by the main grooves adjacent to each other, respectively. The land portions are ribs that are continuous in the tire circumferential direction, and include lug grooves having a semi-closed structure, respectively. Of the main grooves defining the land portions, at least one of the main grooves has a zigzag shape formed by alternately connecting long portions and short portions. Further, a circumferential length Lg2 of the long portion has a relationship 0.70≤Lg2/λ2≤0.90 with respect to a wavelength λ2 of the zigzag shape.

A tire includes a tread portion including first and second tread edges, three or more circumferential grooves, and four or more land portions. The circumferential grooves include a first shoulder circumferential groove nearest to the first tread edge. Each land portion is provided with only sipes and is not provided with lateral grooves. The land portions include a first shoulder land portion having the first tread edge, and a first middle land portion adjacent to the first shoulder land portion. The first middle land portion is provided with first middle sipes traversing the first middle land portion completely in the tire axial direction. The first shoulder land portion is provided with first shoulder sipes extending from the first shoulder circumferential groove to the first tread edge. The first shoulder sipes have a circumferential pitch length smaller than a circumferential pitch length of the first middle sipes.

A pneumatic tire of the present disclosure includes a tread, wherein the tread includes: a shoulder main groove; a plurality of shoulder slits; and a plurality of shoulder blocks defined by the shoulder main groove and the shoulder slits, the shoulder blocks include inclined portions inclined inward in the tire radial direction from the shoulder blocks toward an outside in the tire axial direction, the inclined portions include: first inclined portions; and second inclined portions having dents dented more inward in the tire axial direction than the first inclined portions, and the first inclined portions are adjacent to each other with one of the shoulder slits interposed between the first inclined portions and the second inclined portions are adjacent to each other with other shoulder slit interposed between the second inclined portions, the one shoulder slit and the other shoulder slit being paired and defining the shoulder blocks.

A tread portion 2 includes four circumferential grooves 3 and five land portions 4. Each of the five land portions 4 is provided with no groove having a groove width greater than 2.0 mm, and is provided with only sipes 9. The four circumferential grooves 3 include a shoulder circumferential groove 5. The five land portions 4 include a shoulder land portion 11 and a middle land portion 13. The middle land portion 13 is provided with a plurality of middle sipes 30. The shoulder land portion 11 is provided with a plurality of shoulder sipes 20 each extending from the shoulder circumferential groove 5 to a position beyond a tread end. At least one of the shoulder sipes 20 includes an inclined portion 21. A maximum angle of the inclined portion 21 with respect to a tire axial direction is not greater than a maximum angle of the middle sipe 30 with respect to the tire axial direction. A difference between the maximum angle of the inclined portion 21 and the maximum angle of the middle sipe 30 is not greater than 5°.
