At least one of the first shoulder lateral grooves can include an inner end connected to the first shoulder circumferential groove, a maximum groove width portion, and an outer portion. The maximum groove width portion can be at almost the center, in a tire axial direction, of a ground contact surface of the first shoulder land portion. A groove width at the inner end and a groove width, on a first tread end, of the first shoulder lateral groove can each be less than the maximum groove width. A groove width of the outer portion can be reduced outward in the tire axial direction.

A tire can include a tread, sidewalls, beads, and a carcass. Each bead can include a core and an apex. A ratio of a height of the apex to a cross-sectional height of the tire may be not less than 5% and not greater than 15%. In a meridian cross-section of the tire in a standard state, a contour of a side surface including a maximum width position can include two arcs tangent to each other at the maximum width position. The arc located inward of the maximum width position in a radial direction can be a first arc, and the arc located outward of the maximum width position in the radial direction can be a second arc. A ratio of a first radius of the first arc to a second radius of the second arc may be not less than 70% and not greater than 91%.

Provided is a 5-rib tire that can have improved steering stability and noise performance A tread portion 2 includes four circumferential grooves 3 and five land portions 4. Two tread ends are ends of a 50%-load ground-contact surface. 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 five land portions 4 include a shoulder land portion 11. The shoulder land portion 11 is provided with a plurality of shoulder sipes 20. At least one of the shoulder sipes 20 includes an inclined portion 21 and an axial portion 22. The axial portion 22 cross the tread end.

A tire includes a tread portion including four circumferential grooves extending continuously in the tire circumferential direction and five land portions divided by the four circumferential grooves. The five land portions include a first middle land portion located between a first tread edge and a tire equator. The first middle land portion is provided with first middle sipes inclined with respect to a tire axial direction and fully traversing the first middle land portion in the tire axial direction. Each first middle sipe includes a pair of sipe edges, and at least one of the pair of sipe edges opens at the ground contact surface via a chamfer portion over an entire length thereof. The chamfer portion has a chamfer width increasing continuously from a first longitudinal edge to a second longitudinal edge of the first middle land portion.

A pneumatic tire includes chamfered sipes in a land portion each including a chamfered portion, and non-chamfered sipes in the land portion each not including the chamfered portion. The chamfered sipe includes one end communicating with the main groove that defines the land portion and the other end terminating within the land portion. The chamfered and non-chamfered sipes are alternately disposed in the circumferential direction. Of the non-chamfered sipes on both sides in the circumferential direction of the chamfered sipe, a relationship between a distance a and a distance b is in the range 1.5≤(b/a)≤12, where the distance a is between the chamfered sipe and a near sipe corresponding to the non-chamfered sipe located on a side closest to the chamfered sipe, and the distance b is between the chamfered sipe and the non-chamfered sipe located further from the chamfered sipe in the circumferential direction.

A tire includes a tread portion being provided with a first circumferential groove extending continuously in the tire circumferential direction, and a first land portion adjacent to the first circumferential groove. The first land portion includes a ground contact surface, a land sidewall on a first circumferential groove side, and a recess that opens across both the ground contact surface and the land sidewall. The recess has an opening defined by a V-shaped first edge and a V-shaped second edge respectively extending on the ground contact surface and the land sidewall. The recess has a circumferential maximum length L1 of from 6.0 to 9.0 mm. The recess has a maximum depth d1 of from 15% to 40% of a maximum depth of the first circumferential groove. The recess has an axial maximum length L2 of from 3.0 to 5.0 times the depth d1.

A tire includes a tread portion including a first tread edge, a first shoulder circumferential groove, and a first shoulder land portion demarcated by the first shoulder circumferential groove to include the first tread edge. The first shoulder land portion is provided with first shoulder lateral grooves extending from the first shoulder circumferential groove to the first tread edge. One of the first shoulder lateral grooves includes first and second groove walls which face each other, and a tie-bar. The tie-bar includes an outer surface extending along a ground contact surface of the first shoulder land portion, the outer surface being connected to the first and second groove walls. The outer surface includes a first edge connected to the first groove wall, and a second edge connected to the second groove wall, the second edge having a length smaller than a length of the first edge.

A tire includes a tread portion including a first shoulder land portion provided with first shoulder lateral grooves extending from a first tread edge to a first shoulder circumferential groove, a second shoulder land portion provided with second shoulder lateral grooves extending from a second tread edge and terminating within the second shoulder land portion, a first middle land portion provided with first middle lateral grooves extending from the first shoulder circumferential groove and terminating within the first middle land portion, a second middle land portion provided with outer and inner second middle lateral grooves respectively extending from the second crown circumferential groove and the second shoulder circumferential groove and terminating within the second middle land portion, and a crown land portion provided with crown lateral grooves extending from the first crown circumferential groove and terminating within the crown land portion.

A tire includes a tread formed with: circumferential grooves extending continuously in a tire circumferential direction; lateral grooves connecting the circumferential grooves in a tire axial direction; and blocks divided by the circumferential grooves and the lateral grooves. In the lateral groove, a groove bottom is raised to form a tie bar connecting the blocks in the tire circumferential direction. The tie bar is formed with a groove portion penetrating the tie bar in the tire axial direction. In a state where the tire is assembled to a regular rim, filled with a regular internal pressure, loaded with a regular load, and contacting a flat surface at a camber angle 0°, a side wall formed on the tie bar by the groove portion on one side in the tire circumferential direction does not contact a side wall on the other side in the tire circumferential direction.
