摘要： A tire that includes a tread portion having a designated mounting direction to a vehicle can comprise: an outer shoulder land portion having a greatest width, in the tire axial direction, of a ground contact surface among five land portions. The outer shoulder land portion can include a plurality of outer shoulder sipes connected to an outer shoulder circumferential groove. An outer middle land portion can include a plurality of outer middle sipes extending completely across the outer middle land portion in the tire axial direction. The outer shoulder sipes and the outer middle sipes each can include a pair of sipe walls. The outer shoulder sipes and the outer middle sipes can each include a body portion in which the pair of sipe walls are disposed substantially parallel to each other. A width of a body portion of each outer shoulder sipe can be greater than a width of a body portion of each outer middle sipe.

摘要： A tire includes a tread portion including four circumferential grooves between outboard and inboard tread edges, and five land portions divided by the circumferential grooves. The circumferential grooves include an inboard shoulder circumferential groove located nearest to the inboard tread edge in the circumferential grooves. The land portions include an inboard shoulder land portion disposed axially outward of the inboard shoulder circumferential groove and having a ground contact surface with the smallest axial width in the land portions. The inboard shoulder land portion is provided with inboard shoulder lateral grooves and inboard shoulder sipes. The inboard shoulder lateral grooves include inner ends away from the inboard shoulder circumferential groove. The inboard shoulder lateral grooves extend axially outward from the inner ends to a location beyond the inboard tread edge. The inboard shoulder sipes extends from the inboard shoulder circumferential groove to a location beyond the inboard tread edge.

摘要： 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°.

摘要： 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.

摘要： A tread portion 2 can include an inner tread end, an outer tread end, circumferential grooves, and land portions. The circumferential grooves can include an inner shoulder circumferential groove and an outer shoulder circumferential groove. The land portions can include an inner shoulder land portion and an outer shoulder land portion. The inner shoulder land portion can include inner shoulder lateral grooves and inner shoulder sipes. The outer shoulder land portion can include outer shoulder lateral grooves and outer shoulder sipes. Each outer shoulder sipe can have a chamfered portion at each of sipe edges on both sides. The chamfered portion can have a chamfered width that increases from a terminating end side toward the outer shoulder circumferential groove.

摘要： 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.
