A method having: acquiring pressure distribution data at which there are a plurality of measurement points for which forces along three axes have been measured; calculating friction coefficients based on the forces along the three axes at the respective measurement points; generating associated data, linking a contact patch pressure and a maximum friction coefficient that is capable of being exhibited at the contact patch pressure, for a plurality of situations based on a single situation represented by a contact patch pressure and a friction coefficient exhibited at the contact patch pressure at a single measurement point; identifying maximum friction coefficients corresponding to contact patch pressures at respective measurement points based on the associated data; and calculating a margin of the friction coefficient, which is a difference between the maximum friction coefficient and the friction coefficient.
