Abstract
A method of determining the grip coefficient μ in the contact area of a tire on a road includes the steps of selecting a plurality of fixed points in space (that is to say ones that are fixed in the reference frame associated with the vehicle) which points lie at different azimuths along the circumference in at least one sidewall of the tire, obtaining a corresponding number of measurements of circumferential distance variation (extension or contraction) at these fixed points when the tire is rolling on the road, and the measurement signals are processed so as to extract the grip coefficient μ.
