Abstract: A pneumatic tire (1) comprises a radial carcass (2), a tread portion (7) and a belt reinforcing structure (8) extending circumferentially around the carcass (2). Disposed radially outwardly of the belt reinforcing structure (8) is a textile reinforced overlay structure (9) having substantially circumferentially extending cords (10). The overlay structure (9) is composed of a series of helical convolutions of a textile ribbon (11) whereby adjacent helical convolutions of the textile ribbon (11) overlap. There is further disclosed a method of applying multiple layers of a single continuous helically wound textile ribbon (11) in a single continuous operation from one axial side to the other axial side of the belt reinforcing structure (8).
