<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of reducing passage noise during vehicle traveling while flat spot performance and high-speed durability performance are secured. <P>SOLUTION: In the pneumatic tire 10, a belt 12 is disposed in a tread forming position on the outside in the tire radial direction of a carcass 11, and a belt reinforcing layer 13 is formed by spirally winding a cord in the tire circumferential direction on the outside in the tire radial direction of the belt 12. The cord winding density of the belt reinforcing layer 13 is formed lower in the center in the tire width direction than the end in the tire width direction, and a distance in the tire radial direction from the surface of the belt 12 to the surface of the tread 14 is formed longer in the center in the tire width direction than in the end in the tire width direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
