<p><P>PROBLEM TO BE SOLVED: To provide a tire capable of improving snow road performance by suppressing the fall of a land part block in a tire circumferential direction. <P>SOLUTION: The tire is provided with a main block 22 and a sub-block 82, and a sipe 100 is formed on the main block 22. The height of the sub-block 82 from the groove bottom of a circumferential groove is lower than the height from the groove bottom to the main block 22. A first lateral groove 110 is formed on a connection part between one end part of the sub-block 82 in a tire circumferential direction TC and the main block 22 continuing into the end part, and a second lateral groove 120 is formed on a connection part between the other end part of the sub-block 82 in the tire circumferential direction TC and the main block 22. One end of the first lateral groove 110 is opened to one circumferential groove side, and the other end of the first lateral groove 110 is terminated in the middle of the connection part. One end of the second lateral groove 120 is opened to the other circumferential groove side, and the other end of the second lateral groove 120 is terminated in the middle of the connection part. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
