<P>PROBLEM TO BE SOLVED: To improve drainage performance in the whole area of a tread by shaping water which is divided and merged at a joint between a circumferential groove and an inclined groove. <P>SOLUTION: The tire 1 has, on the tread, the circumferential groove 11 extending a tire circumferential direction X and the inclined groove 12 extending with an inclination relative to a tire width direction Y. At least one end of the inclined groove 12 is configured to be opened to the circumferential groove 11. A projection 20 is formed at a part of a bottom 11A of the circumferential groove 11 and a bottom 12A of the inclined groove 12, and the projection 20 has a circumferential projection 21 extending in the tire circumferential direction X in the bottom 11A of the circumferential groove 11 and a branched projection 22 branched and extended from the circumferential projection 21. <P>COPYRIGHT: (C)2013,JPO&INPIT |
