Patent ID: 6851307

Claim:
A method for determining a transverse component (Fy) of a resultant of forces exerted through the roadway ( 3 ) on a contact area ( 2 ) of a tire ( 1 ), comprising the steps of: measuring a first angular circumferential deformation (δf(B)) in a first side wall ( 4 ) of the tire ( 1 ) at a first fixed point (B) in space which is located at an azimuth (φ) along the circumference of the tire ( 1 ), which azimuth differs from an azimuth of the center of the area of contact ( 2 ) and differs from an azimuth of the point opposite the center of the area of contact ( 2 ), measuring a second angular circumferential deformation (δa(B)) in a second side wall ( 4 ′) of the tire ( 1 ) at a second fixed point (C) in space which is located at an azimuth (−φ) along the circumference of the tire ( 1 ), which azimuth differs from an azimuth of the center of the area of contact ( 2 ) and differs from an azimuth of the point opposite the center of the area of contact ( 2 ), and, determining from a difference between the first and second angular measurements a transverse component (Fy) of resultant forces.
