  • Patent number: 11772428
    Abstract: A tire has a tread portion comprising a first land region divided by a circumferential groove extending continuously in the tire circumferential direction. The first land region is provided with first lateral grooves extending thereacross to circumferentially divide the first land region into blocks. The blocks include a first block provided with a second lateral groove and sipes. The second lateral groove has two end portions which are inclined with respect to the tire axial direction to a first direction toward one side in the tire axial direction, and a central portion between the two end portions which is inclined with respect to the tire axial direction to a second direction opposite to the first direction toward the above-said one side in the tire axial direction.
