Abstract

L'invention vise à proposer un pneu à affaissement limité (1) pour améliorer un confort de conduite tout en améliorant une durabilité de roulage à plat. Le pneu à affaissement limité (1) comprend une carcasse (6), une couche de ceinture (7) ayant deux nappes de ceinture (7A et 7B) à l'intérieur et à l'extérieur d'un rayon de pneu, et une couche de caoutchouc de renfort latéral (11) ayant une section sensiblement en croissant. La carcasse (6) comprend une nappe de carcasse (6A) ayant des câbles de carcasse disposés en réseau à un angle de 70 à 90 degrés par rapport à la direction de la circonférence du pneu et revêtus d'un caoutchouc de sommet, et les câbles de carcasse sont réalisés en câble de fibre d'aramide ayant un coefficient de torsion (T) de 0,50 à 0,70. Le pneu à affaissement limité (1) comprend en outre une couche de caoutchouc de renfort de bande de roulement (9) interposée entre la couche de ceinture (7) et la carcasse (6) et ayant une dureté de 70 degrés ou plus et un facteur de dissipation (tanδ) de 0,15 ou moins.
