PROBLEM TO BE SOLVED: To provide a pneumatic tire improved in durability performance while maintaining a braking performance on ice. ! SOLUTION: There is provided a pneumatic tire in which plural blocks 16 are formed by the pluralities of circumferential grooves 12 and inclined grooves 14, and at least one sipe 18 extending while curving in the tire width and radial directions is arranged on each block 16. In at least one sipe 18 of the pneumatic tire, a virtual extending direction on a block surface S (direction of a full line 18a) is different from that on a sipe bottom B (dotted line 18b). The virtual extending direction on a sipe bottom B is inclined to the tire width direction. ! COPYRIGHT: (C)2015,JPO&INPIT |
