摘要： A pneumatic tire has a tread that is provided with a plurality of blocks comparted in a tire circumferential direction by a lateral groove. A sipe formed in each of the blocks has a narrow portion that is open in a tread surface, and a wide portion that is communicated with an inner side in a tire diametrical direction of the narrow portion and is widened than the narrow portion. The wide portion gradually increases a widening length in one side in a width direction and gradually decreases a widening length in other side in the width direction, from one end portion of the sipe toward other end portion, and accompanies an angle change at a time of appearing on the tread surface due to a progress of a wear.

摘要： A tire comprises a tread portion including a first land portion provided with axially extending first lateral sipes. The first lateral sipe has a first sipe wall and a second sipe wall, and opens at a ground contacting top surface via a chamfer portion. The chamfer portion comprises a first sloped surface and a second sloped surface respectively connected to the first sipe wall and the second sipe wall. In a top view of the first land portion, the width W1 of the first sloped surface is larger than the width W2 of the second sloped surface.

摘要： A center land has first center notches, second center notches, center slits, a first land end and a second land end. The first center notches and the center slits open onto the first land end in alternating fashion as one proceeds along a tire circumferential direction. The second center notches and the center slits open onto the second land end in alternating fashion as one proceeds along the tire circumferential direction. A quarter land has first quarter slits, first quarter notches, second quarter slits, second quarter notches, a third land end and a fourth land end. The first quarter slits and the first quarter notches open onto the third land end in alternating fashion as one proceeds along the tire circumferential direction.

摘要： A tread for a heavy truck tire is provided that has a bottom surface (14), a shoulder rib (16), and a sacrificial rib (20) located outboard from the shoulder rib (16) in a width direction. A decoupling void (30) is located between the shoulder rib (16) and the sacrificial rib (20). First decoupling void sipes (32), second decoupling void sipes (100) and third decoupling void sipes (104) are in the shoulder rib (16), and one second decoupling void sipe (100) is between one first decoupling void sipe (32) and one third decoupling void sipe (104). The first and third decoupling void sipes (32, 104) are closer to the bottom surface (14) than is the decoupling void (30) in the thickness direction. The second decoupling void sipe (100) is not closer to the bottom surface (14) than is the decoupling void (30) to the bottom surface (14) in the thickness direction.

摘要： A tire includes a block group delimited by a pair of circumferential grooves extending in a tire circumferential direction. The block group includes a plurality of blocks delimited by a plurality of lateral grooves extending in the tire width direction. Each block of the plurality of block group is partitioned into a plurality of small blocks by a circumferential sipe and a plurality of lateral sipes. In each block, the circumferential sipe extends in a zigzag shape, and at least an outermost lateral sipes of the plurality of lateral sipes in the tire circumferential direction extend in parallel with each other.

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： The tire includes a tread portion having circumferential grooves extending in a tire circumferential direction and land regions demarcated by the circumferential grooves. The circumferential grooves include a first circumferential groove and a second circumferential groove adjacent to the first circumferential groove and having a width larger than the first circumferential groove. The land regions include a first land region demarcated between the first circumferential groove and the second circumferential groove. The first land region has lateral grooves extending in a tire axial direction and lateral sipes extending in the tire axial direction and each having a width smaller than that of each of the lateral grooves. A total value of the widths of the lateral grooves and the lateral sipes connected to the second circumferential grooves is smaller than a total value of the widths of the lateral grooves and the lateral sipes connected to the first circumferential grooves.

摘要： A tire includes: main grooves provided in a tread; an intermediate land provided between a first main groove and a second main groove from a vehicle outer side; a first sipe extending through the intermediate land in a width direction; and a first lug groove open to the first main groove. The first sipe is bent in the intermediate land. The first sipe includes a first portion on one side of the bent portion in the width direction, inclined with respect to a circumferential direction, and open to the second main groove and a second portion on the other side of the bent portion in the width direction, inclined toward a side opposite to the first portion with respect to the circumferential direction, and open to the first main groove. Extension lines of the second portion and a groove center line of the first lug groove are substantially parallel.
