发明名称 TIRE
摘要 A tire that can suppress uneven wear of the tread surface while maintaining steering stability and drainage performance on wet road surfaces is provided. In the tire, a plurality of land portions are defined in a tread surface by a plurality of circumferential grooves extending in a tire circumferential direction, and each of the plurality of land portions has a plurality of lateral grooves crossing the land portion. The plurality of lateral grooves are arranged so that, when the plurality of lateral grooves are projected onto a tire equatorial plane, lateral grooves adjacent in the tire circumferential direction do not overlap each other. Each of the plurality of lateral grooves is made up of a center region extending at an angle of inclination relative to a tread width direction and side regions extending from both ends of the center region toward respective circumferential grooves at a smaller angle of inclination relative to the tread width direction than the center region, the side regions increasing in groove width toward the respective circumferential grooves. Each of the plurality of lateral grooves has a sipe leading inward in a tire radial direction from a groove bottom of the lateral groove, and the sipe has, only in the center region, a shallow portion with a smaller depth, the shallow portion being located at least near a boundary part between the center region and each of the side regions with a starting point of the shallow portion being apart from the boundary part.
