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.

A tread pattern of a pneumatic tire includes an inner circumferential main groove and an outer circumferential main groove that have groove walls extending in a tire circumferential direction while the angle of the groove walls relative to a contact surface varies with a predetermined amplitude, an inner lug groove extending from the inner circumferential main groove toward the outer circumferential main groove, an outer lug groove extending from the outer circumferential main groove toward the inner circumferential main groove, and a sipe configured to communicate the inner lug groove with the outer lug groove. A pair of chamfered surfaces are provided on walls of the sipe along an extension direction of the sipe on the contact surface.

A tyre includes a tread portion including a first land portion having a circumferentially extending first edge and a circumferentially extending second edge on its ground contacting surface. The first land portion is provided with sipes each extending from the first edge to the second edge. The sipes include bent sipes each including two or more sipe elements joined with each other to form a bent portion. The bent sipes include first sipes and second sipes. Each first sipe, as the sipes elements, includes at least one first sipe element inclined in a first direction with respect to a tyre axial direction and at least one second sipe element inclined in a second direction opposite to the first direction with respect to the tyre axial direction. All sipe elements of each second sipe are inclined in the first direction with respect to the tyre axial direction.

Embodiments of the disclosure include pneumatic tires having improved snow performance. Said tires include a cap ply extending at least partially across a full width of at least one of the belt plies and having a rupture force greater than 210 N per 15 mm of cap ply width. A shoulder rib includes a compliance groove or sipe extending primarily in a circumferential direction and to a depth equal to or less than 75% of the skid depth. The lateral sipes and grooves are arranged to provide an average lateral feature spacing of less than 15 mm. The average inclination angle for the lateral grooves is greater than 6 degrees in the shoulder ribs and is greater than 20 degrees in the central ribs. A longitudinal non-lateral sipe edge density is greater than 21.1 micrometers/mm.sup.2. A longitudinal lateral sipe edge density for all lateral sipes is greater than 5.5 micrometers/mm.sup.2.

A tire includes a tread portion including a first land portion, the first land portion being provided with a plurality of first sipes. The plurality of first sipes extends in an arc shape manner. The plurality of first sipes is arranged on the first land portion without communicating with lateral grooves extending in a tire axial direction. In a tread plan view, a virtual sipe reference line of each of the plurality of first sipes has an angle equal to or less than 10 degrees with respect to a tire circumferential direction, wherein the virtual sipe reference line is a straight line that connects both ends of each of the plurality of first sipes.

A tire includes a tread portion. The tread portion has a main groove extending continuously in a tire circumferential direction, and a land portion adjacent to the main groove. The land portion has lateral grooves extending from the main groove in a tire axial direction. Each of the lateral grooves has a first portion communicating with the main groove, and a second portion connected to the first portion. The first portion has a larger groove width than the second portion and has a smaller groove depth than the second portion.

A tire includes a tread portion provided with a first land region demarcated between a shoulder circumferential groove and a tread edge. The first land region is provided with first sipes extending in a tire circumferential direction, axial sipes, and first axial grooves extending from the tread edge. The first sipes are not connected with the first axial grooves. Each of the axial sipes has an axially inner end connected with the shoulder circumferential groove. Each of the axial sipes has an axially outer end connected with one of the first sipes.

A pneumatic tire has paired bead portions, paired sidewall portions, a tread portion, a plurality of lug grooves extending from a shoulder area of the tread portion to reach a buttress area of the sidewall portion, and a block defined by the plurality of lug grooves. The block includes a shoulder block provided in the shoulder area, and a buttress block provided in the buttress area. The buttress area is provided with an annular rib annularly extending along a tire circumferential direction. The lug grooves are comparted into an outside lug groove positioned in an outer side of the annular rib, and an inside lug groove positioned in an inner side of the annular rib. A widened portion is provided in at least part of the plurality of lug grooves so as to enlarge a width of the annular rib.

In a tire tread pattern, inclined grooves extend from a starting end in a center region including an equator toward both sides in a width direction and toward the same side in a circumferential direction to a pattern end. A periphery distance from the equator to the pattern end at an outer side in the width direction being 100%, in ranges separated from the starting end by ≤35%, from >35% to ≤50%, from >50% to ≤70% and from >70% to ≤100%, an inclination angle of the inclined grooves relative to the circumferential direction is from >40° to ≤50°, from >50° to ≤65°, from >65° to ≤80°, and from >80° to ≤90°, respectively. A circumferential-direction distance from the starting end to a terminating end of the inclined grooves is 60% to 90% of a width-direction distance.
