PROBLEM TO BE SOLVED: To provide a pneumatic tire which improves wet braking property while maintaining the rolling resistance. SOLUTION: The pneumatic tire is equipped with a plurality of blocks 3 divided by circumferential grooves 1 extending circumferentially on a tread and widthwise grooves 2 extending in the direction crossing the circumferential grooves 1 on tread. In this case, circumferential sipes 4, which extend in the tread circumference from the widthwise grooves 2 and remains in the blocks, are provided on the blocks 3. This pneumatic tire has at least one block row where a plurality of the blocks 3 are arranged in the tread circumference and the blocks 3 of the block row are connected mutually via blocks 3 continued in the tread circumference.
