ABSTRACT:
The overall deformation of a tire is measured by using two reference points in different parts of or at least in close proximity to different parts of the rim of the wheel, the reference points are spaced apart in a direction transversely to the plane of rotation of the tire; two transducers are respectively connected to the reference points and to the same particular point on the inside of the tire opposite the running surface to establish a triangle in a cross sectional radial plane of the tire; each of the transducers includes a force sensing element responsive to the change in distance between the respective reference point and the measuring point; the transducers further including tension springs to establish mobility as between the measuring and reference points.
