Method of quantifying a use of the maximum grip potential of a tyre

摘要

The method involves determining two values of differential extension of a tread (14) of a tire (10) or shearing of the tread homogeneous at an extension in two distinct azimuths. Use of maximal grip potential is quantified using the values. The azimuths define an acute angular sector with a contact area of the tread in contact with ground. The extension corresponds to difference between the extension values of the tread, where the difference is measured symmetrically with respect to an equatorial plane of the tire. An independent claim is also included for a tire having two extension sensors.
