The overlay structure comprises a single ribbon (22) of side-by-side textile cords spirally wrapped about the belt structure such that both ends of the ribbon are in close proximity to the equatorial plane (EP) of the tire, while the axial width of the overlay structure is at least equal to that of the belt structure. The number of radial layers of cords in the overlay structure being greater at the axial edges of the belt structure than the average number of radial layers of cords in the remainder of the overlay structure. A method of manufacturing such an overlay structure is also disclosed.
