<P>PROBLEM TO BE SOLVED: To provide a tire which secures sufficient drainability and driving stability even when attached to an automobile having torque set high in a low-revolution area, such as an electric car and a hybrid-type automobile. <P>SOLUTION: In the pneumatic tire 10, an inclined groove 200 elongated to a tread shoulder 30 from a central portion 25 in a tread width direction D<SB POS="POST">T</SB>and inclined with respect to the circumferential direction D<SB POS="POST">C</SB>of the tire is formed on a land portion 20 brought into contact with a road surface. A plurality of ribbed protrusions 210 elongated along the circumferential direction D<SB POS="POST">C</SB>of the tire are formed in the inclined groove 200. One end, in the radial direction D<SB POS="POST">R</SB>of the tire, of the ribbed protrusion 210 continues into one side wall of the inclined groove, and the other end, in the radial direction D<SB POS="POST">R</SB>of the tire, of the ribbed protrusion 210 is provided apart from the other side wall of the inclined groove 200. <P>COPYRIGHT: (C)2013,JPO&INPIT |
