Tire overturning moment measurements have traditionally been used primarily for rollover threshold analysis, and have often been ignored for linear range maneuvers. This paper explains how overturning moment is related to aligning torque for a tire under tractive force. This relationship can be used to develop a better understanding of tire properties necessary to achieve better steering refinement. A free rolling overturning moment measurement is shown to provide useful information for aligning torque performance. Example force and moment test results are shown to illustrate the concepts.
