A method and system for determining the potential friction between a tire and a rolling surface wherein: the tire is rotated on the rolling surface so as to subject a crown portion of the tire to an acceleration radial component; data are obtained which are representative of the acceleration radial component to which the crown portion is subjected during at least one tire revolution; starting from the data, data are selected which are representative of at least one transition region of the acceleration radial component; the selected data are processed so as to obtain information correlated with the steepness of transition of the at least one transition region; and the potential friction is estimated on the basis of the information correlated with the steepness of transition.
