Tyre with reduced rolling noise

摘要

The tire (1) has a crown extended through side walls and beads, where a base of the crown is mounted on a base of a rim (7). A carcass reinforcement structure is anchored in the beads. An additional cellular layer (10) is connected to edges of a structure of the tire and is not connected outside. The layer is cooperated with an internal wall of the tire to form a cavity (15) sealed to air, where the layer includes an inflation valve (11). A self-sealing material layer (40) placed between the structure and layer contains glycol, fibers, vulcanized rubber particles or cellular particles. An independent claim is also included for a method for fabricating a tire.
