車両ホイール用防音セルフシールタイヤ
車両ホイール用防音セルフシールタイヤ
The present invention relates to soundproof self-sealing tyres for vehicles wheels and to processes for the manufacture thereof. In particular, the soundproof self-sealing tyres of the invention comprise closed-cell foamed polyolefin materials, preferably with closed macrocells, optionally perforated. These noise-reducing materials surprisingly allow maintaining the sealing performance of traditional self-sealing systems, which are instead compromised in the case of conventional noise-reducing materials based on open-cell foamed polyurethanes.
