<p><P>PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of sufficiently inhibiting the uneven wear of a shoulder rib and reducing the occurrence of the cracks of a shoulder groove. <P>SOLUTION: A groove wall surface 12a of a shoulder groove 12 on a shoulder land 18 side is configured to be a slope comprising a first inclination 121 inclined at an inclination angle ofθ<SB POS="POST">1</SB>on a tire equatorial plane side and a second inclination 122 inclined at an angle ofαrelative to the first inclination 121. At the same time, a plurality of groove wall sipes 20 which are open to the shoulder groove 12 in the second inclination 122 and whose extending direction is vertical to a curve Q connecting boundaries between a groove bottom 12b of the shoulder groove 12 and the second inclination 122 when viewed from the tread surface side of the tire is arranged in the circumferential direction of a tire. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
