Abstract
To provide a tire that can be improved in noise performance during acceleration running, while maintaining hydroplaning performance.SOLUTION: A tire 1 comprises a tread part 2. In the tread part 2 are formed a plurality of circumferential grooves 3 extending in a tire circumferential direction and a plurality of land parts 4 partitioned by the plurality of circumferential grooves 3. Total of groove widths of the plurality of circumferential grooves 3 are above 20% of a grounding width TW. At least one of the land parts 4 is provided with a plurality of lateral sipes 5 extending in a tire axial direction. All of the lateral sipes 5 terminate in the land parts 4 without communicating end parts arranged adjacently to the circumferential grooves 3 with the circumferential grooves 3.SELECTED DRAWING: Figure 1
