Several tyre manufacturers have already utilised foam as noise reduction solution, and now Falken Tyre has presented its own version – which it says can lower drive-by noise by up to ten decibels compared to standard tyres and cabin noise by four decibels. The solution was material developed together with parent company Sumitomo Rubber Industries (SRI) and consists of a double-humped layer of ether-polyurethane foam material. Falken calls it Silent Core.
