摘要： A soundproof tyre and a process for the production thereof. The tyre includes particular polyolefin sound absorbent foams that provide damping for noise generated in a cavity of the tyre, together with resistance to hydrolysis, poor water absorption and an unexpected thermal and mechanical stability in use conditions. The sound absorbent material is applied on at least a portion of a radially inner surface of the tyre. The portion of the radially inner surface includes an impermeable elastomeric material layer. The sound absorbent material includes a foamed polyolefin material with closed macrocells having an average size of at least 1.5 mm according to ASTM D357 6.
