Abstract
There is provided a pneumatic tire capable of improving high-speed durability and noise characteristics. The pneumatic tire has a belt-reinforcing structureradially outwardly of belt pliesand, the belt-reinforcing structurehaving organic fiber cords n spirally wound in the circumferential direction T of the tire. The belt-reinforcing structurehas an end reinforcement layerB disposed radially outwardly of each end region BE of the belt pliesand. The end reinforcement layerB has a two-layer structure in which its organic fiber cord nb formed of a hybrid cord is spirally wound from the axially inner side of the tire toward the axially outer side of the tire, is turned in an opposite direction at an edgeof the belt-reinforcing structure and is spirally wound from the axially outer side of the tire toward the axially inner side of the tire, and in which the opposite edges of the organic fiber cord nb are away inwardly in the axial direction of the tire from the edgeof the belt-reinforcing structure.
