Claim 6:
7. The method according to claim 5, wherein, during rolling, over the course of one revolution of the wheel, the curvature of the tire changes according to a cycle exhibiting:
a part not in contact with the ground, characterized in the measurement signal by a stable curvature;
a part in contact with the ground, characterized in the measurement signal by a spike of variation of contact curvature;
a transition referred to as the coming-into-contact transition between the part not in contact with the ground and the part in contact with the ground, characterized in the measurement signal by a coming-into-contact curvature variation spike that is the opposite of the spike of variation of contact curvature;
a transition referred to as the coming-out-of-contact transition between the part in contact with the ground and the part not in contact with the ground, characterized in the measurement signal by a coming-out-of-contact curvature variation spike that is the opposite of the spike of variation of contact curvature;
the first parameter being determined from a distance between the coming-into-contact curvature variation spike and the coming-out-of-contact curvature variation spike; and
the second parameter being determined from a gradient between the coming-into-contact curvature variation spike and the variation spike of contact curvature.
