Abstract

L'invention concerne un pneu de véhicule qui possède une couche intérieure (4a, 4b) qui est étanche à l'air dans une très large mesure, ainsi qu'un anneau (7) insonorisant en mousse qui adhère à la surface intérieure opposée à la bande de roulement (1), l'anneau de mousse (7) adhérant à une couche d'adhésif (5) appliquée préalablement. En coopération avec l'anneau de mousse (7), la couche d'adhésif (5) présente une très grande étanchéité à l'air, de telle sorte qu'à l'endroit où l'anneau de mousse (7) est appliqué sur la surface intérieure du pneu, il n'est pas disposé de couche intérieure étanche à l'air.
