A pneumatic tire includes circumferential main grooves extending in the tire circumferential direction and a land portion defined by the circumferential main grooves. The land portion includes a through lug groove that passes through the land portion in the tire lateral direction and includes first and second chamfered portions formed on left and right edge portions of the through lug groove. The first chamfered portion opens at one end to one of the edge portions of the land portion and terminates at the other end at a central portion in the groove length direction of the through lug groove. The second chamfered portion opens at one end portion to one of the edge portions of the land portion and terminates at the other end portion at a central portion in the groove length direction of the through lug groove.

A tire has a tread portion 2 including a first land portion 11. The first land portion 11 includes a first circumferential edge 11a, a second circumferential edge 11b, and a tread surface between the first circumferential edge 11a and the second circumferential edge 11b. On the tread surface, a first inclined groove 21 extending from the second circumferential edge 11b to the first circumferential edge 11a side, a second inclined groove 22 extending from the second circumferential edge 11b to the first circumferential edge 11a side so as to be inclined in a direction opposite to that of the first inclined groove 21, and a triangular block 35 demarcated by the first inclined groove 21 and the second inclined groove 22, are formed. A curved groove 15 curved so as to be convex on the second circumferential edge 11b is formed on the triangular block 35.

A pneumatic tire includes lug grooves having alternating first and second groove portions. The first groove portion intersects an equator, extends in a width direction, and communicates with an adjacent second groove portion. The second groove portion inclines from the first groove portion at a smaller angle relative to a circumferential direction smaller than that of the first groove portion and extends to a tread edge on one side. The first groove portion is on a stepping side with respect to an end on the tread edge side. The second groove portions curve or bend and have an average angle in an inner region smaller than that of the second groove portions in an outer region. A maximum length in the width direction of center blocks defined by narrow grooves connecting adjacent second groove portions and the lug grooves is 25%-35% of a development width.

A tire having a tread portion with a designated mounting direction. An outer shoulder land portion has outer shoulder lateral grooves. An inner shoulder land portion has inner shoulder lateral grooves. Each outer shoulder lateral groove includes a first outer portion extending in a tire axial direction at an outer tread edge side, and a second outer portion that connects the first outer portion to an outer shoulder main groove and that has a smaller groove width and groove depth than the first outer portion. Each inner shoulder lateral groove has a tie bar raised at a groove bottom thereof. The tie bar is connected to the inner shoulder main groove.

A tread portion includes a groove having first and second groove walls opposing each other, at least one first recess formed by partially recessing the first groove wall, and at least one second recess formed by partially recessing the second groove wall. A depth of each of the first and second recess from a ground contact surface is less than a groove depth of the groove. The first recess includes a first opening disposed at the first groove wall, and a first end portion extending substantially parallel to the first opening at a position farthest from the first opening. The second recess includes a second opening disposed at the second groove wall, and a second end portion extending substantially parallel to the second opening at a position farthest from the second opening. The first and second end portions are disposed so as not to oppose each other through the groove.

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 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.
