Tire force generation and transmission properties have been studied over the past 50 years with increased precision and fidelity, with the major physical limitation being the dynamic response bandwidth of the force measuring system. The principles and data presented demonstrate a method of vibration measurement that can allow the separation of machine and tire contributions to the load cell measured forces, thus the extraction of tire signatures. This technique has produced calibrated force measurements that are flat from 0 - 1100 Hz. Tire test data and machine calibration data for passenger tires are shown, both with and without DFMS analysis, demonstrating a significantly increased bandwidth in tire force measurements.
