ABSTRACT:
A measurement technique determines the physical features of a tire such as a determination of the deformation a tire undergoes during use. The measurement technique utilizes a first belt, or first and second belts, in the tire reinforced with a plurality of metallic wires and involves the steps of providing a signal between a first and a second metallic wire associated with the first or first and second belts. The measurement technique determines a real part and an imaginary part of the impedance between the first and second metallic wires, which is proportional to the forces acting on the tire.
