Abstract
A pneumatic tire includes a belt layer, a tread arranged radially outwardly of the belt layer, and reinforcing layers arranged between the tread and the belt layer at both ends of its width directions, respectively. Each of the reinforcing layers consists of a belt-like member having a plurality of cords in parallel with each other embedded therein. The belt-like member is spirally wound about the both ends of the belt layer from inside to outside of a width direction of the belt layer. A terminal portion of the belt-like member is bent inwardly in the width direction of the belt layer to overlap at least one of cords of the terminal portion and at least one of cords of the belt-like member adjacent thereto, thereby preventing the terminal portions of the belt-like members from being dislodged from the tread and deformed and cords of the terminal portions from separating from the tread even after being used for a long period of time.
