<p><P>PROBLEM TO BE SOLVED: To provide a tire for generating a ply steer residual cornering force while restraining uneven wear. <P>SOLUTION: A plurality of center lug grooves 12, 14 are formed at a center land A2 of a pneumatic tire 1, and a plurality of shoulder lug grooves 10, 16, 20, 22, 28, 30 are formed on shoulder lands A1, A3. Shoulder peripheral grooves 51, 57 are formed at the shoulder lands A1, A3. The shoulder lands A1, A3 include first shoulder lands 102, 106 partitioned at the outer most part of a tread width direction TW. Outer lug groove anglesθ1,θ5 formed by straight lines along shoulder lug sipes 20, 30 formed on the first shoulder lands 102, 106 and straight lines along the shoulder peripheral grooves 51, 57 are larger than lug groove anglesθ2,θ4 formed by straight lines along shoulder sipes 22, 28 formed on second shoulder lands 104, 114 and straight lines along the shoulder peripheral grooves 51, 57. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
