VHC RALLY TYRE / XAS FF (FORMULA FRANCE)
XAS with special competition compound "FormuleFrance"

FF stands for Formula France, which is a tyre tread with a mixture that was specifically developed for competition.

It was the first standard tyre designed to run at 210 km/h (131 mph) and its exceptional performance naturally led to the XAS FF being used in Formula France racing from 1968 onwards, circuit racing, rallies and hill climbs.
