<p><P>PROBLEM TO BE SOLVED: To suppress the generation of noise while maintaining wet performance. <P>SOLUTION: Outer longitudinal grooves 12a, 12b are extended in a zigzag pattern in the tire circumferential direction. A plurality of first lateral grooves 13a, 13b located at an outer portion 14 of a tread 11 are gradually extended toward one side in the tire circumferential direction S and continued to the outer longitudinal grooves 12a, 12b when going from the outer side toward the inner side in the tire width direction H. A plurality of second lateral grooves 13c, 13d located at an inner portion 15 of the tread 11 are gradually extended toward one side in the circumferential direction S and continued to the outer longitudinal grooves 12a, 12b when going from the inner side toward the outer side in the tire width direction H. Individual positions in the tire circumferential direction where a plurality of first lateral grooves 13a, 13b are located in the outer portions 14 and the individual positions in the tire circumferential direction where a plurality of second lateral grooves 13c, 13d are located in the inner portions 15 coincide with each other. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
