A speed rated tire (10) is provided with an overlay structure (20) disposed radially outwardly of the belt structure (17). 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.
Pneu conçu pour les hautes vitesses (10) comportant une structure de recouvrement (20) placée radialement vers l'extérieur de la structure de la ceinture (17). La structure de recouvrement comprend une bande unique (22) de fils câblés textiles côte-à-côte enroulés en spirale autour de la structure de la ceinture de sorte que les deux extrémités de la bande sont très près du plan équatorial (EP) du pneu, tandis que la largeur axiale de la structure de recouvrement est au moins égale à celle de la structure de la ceinture. Le nombre de couches radiales de fils câblés dans la couche de recouvrement est plus grand dans les bords axiaux de la structure de la ceinture que le nombre moyen de couches radiales de fils câblés dans le reste de la structure de recouvrement. La méthode de fabrication de cette structure de recouvrement est également décrite.
