Abstract
A method of determining a friction coefficient μ in a contact area of a tire on a road. Fixed points are selected that lie at different azimuths along a circumference of at least one bead of the tire. A shear stress value is measured at each of the fixed points while the tire is rolling on the road. The measured shear stress values are processed to determine the friction coefficient μ.
