Racetrack debut for guayule rubber tyre

Several tyre makers plan to offer tyres containing natural rubber from non-conventional sources. Bridgestone Americas has been working to commercialise guayule shrub rubber for a decade and recently announced the upcoming motorsport debut of a race tyre made with guayule rubber grown and extracted at its R&D facilities. It will introduce the new Firestone Firehawk at the Indy Pit Stop Challenge on 27 May ahead of the race tyre’s competitive premiere in August.
