<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire having directional patters, in which wet performance, on-snow performance, and uneven wear property are improved. <P>SOLUTION: The pneumatic tire includes a plurality of blocks 5 formed in a center C by a center main groove 1, an outside main groove 2, and a side groove 3, and a rag groove 4 formed in the rib 5 of a shoulder S. Directional patterns are formed such that the side grooves 3 located in both sides of a tire width direction with respect to the center main groove 1 are inclined to opposite directions with respect to a tire equator, the center side inclination angle θ1 of the side groove 3 is made a sharp angle, the side grooves 3 of both sides of the tire width direction of the center main groove 1 are arranged to be shifted from each other in a tire peripheral direction so that a peripheral component 3' projecting the side groove 3 in the tire peripheral direction is present in the entire tire periphery, and sipes 7 are formed in blocks 5 and ribs 6. <P>COPYRIGHT: (C)2012,JPO&INPIT |
