<p><P>PROBLEM TO BE SOLVED: To provide a tire which can establish a high-level compatibility between drainage and driving stability. <P>SOLUTION: The tire includes a land portion which is extended in a tire circumferential direction and divided by a circumferential direction groove extended in the tire circumferential direction. A circumferential direction sipe extended in the tire circumferential direction is formed in the land portion. In the land portion, there are provided a first inclined groove which is not only extended from a side in the tread width direction of the land portion but also inclined in the tire circumferential direction and a second inclined groove which is not only extended from the other side in the tread width direction of the land portion but also inclined in the tire circumferential direction. The first and second inclined grooves are alternately formed in the tire circumferential direction. The circumferential direction sipe includes a first circumferential sipe which is formed extended from an end of the land portion side of the first inclined groove to an intermediate part in the tread width direction of the second inclined groove and a second circumferential direction sipe extended from the intermediate part in the tread width direction of the second inclined groove along the extended line of the first circumferential direction sipe. The second circumferential direction sipe terminates in the land portion. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
