<P>PROBLEM TO BE SOLVED: To provide a tire with reduced tire noise such as pattern noise and road noise while securing water discharge performance. <P>SOLUTION: The tire has a plurality of lands formed of a main groove extending along a tire circumference direction. The land includes: a first land having a first groove wall that forms one wall surface of the main groove; and a second land having a second groove wall that forms the other wall surface of the main groove. A lateral groove is formed extending from the first land to the second land. The lateral groove includes: a first lateral groove extending in a direction intersecting the tire circumference direction on a tread surface of the first land with one end thereof opened to the main groove; a second lateral extending in a direction intersecting the tire circumference direction on a tread surface of the second land with one end thereof opened to the main groove; and an in-groove groove communicating to one end of the first lateral groove and one end of the second lateral groove in the main groove. The in-groove groove has a bent portion in the first groove wall or the second groove wall bending from the tire circumference direction to a direction intersecting the tire circumference direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
