ABSTRACT:
A pneumatic tire includes a tread, a pair of sidewalls and a pair of bead portions and further a carcass and a belt for reinforcing the tread, sidewalls and bead portions. The carcass consists of at least one layer of rubber coated cord ply whose organic fiber cords are arranged in parallel with each other in substantially radial surfaces of the tire. The belt consists of a rubber coated metal cord layer folded at least at one edge, whose metal cords are arranged in parallel with each other at relatively small angles with respect to an equatorial line of the tire.
According to the invention, a reinforcing layer of at least one rubber coated layer is arranged in an inside of and in substantially intimate contact with the folded edge of the rubber coated metal cord layer of the belt and extending at least 7% of an overall width of the belt from a folded position of the belt. Cords of the reinforcing layer are organic fiber cords and are in parallel with each other at angles of 0.degree.-40.degree. with respect to the equatorial line of the tire.
