Abstract:
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.
