For evaluation of vehicle handling, subjective assessment is currently almost the only criterion. For the purpose of reducing cycle time and avoiding error of subjective assessment, the close-loop objective evaluation system through computer simulations has become an inevitable choice (Gwanghun, G.I.M. and Yongchul, C.H.O.I., 2001, Role of tire modeling on the design process of a tire and vehicle system, ITEC ASIA 2001, Busan, Korea, September 18-20; Guo, K., Ding, H., Zhang, J., Lu, J. and Wang, R., 2003, Development of longitudinal and lateral driver model for autonomous vehicle control, International Journal of Vehicle Design, 36(1), 50-65). For this reason, the more accurate models of vehicle, tire and driver are necessary. Since structure and operating conditions of tires are very complicated, many researchers have paid more attention to the modeling of tire propertiers and varieties of tire model have been done to describe the tire behaviour of longitudinal, lateral forces and aligning moment (Pacejka, H.B., 2002, Tyre and Vehicle Dynamics, Butterworth-Heinemann, an imprint of Elsevier Science, ISBN 0-7506-5141-5). However, there are few studies for the tire overturning moment (TOM), especially under large slip angle and camber angle. For the simulation of vehicle rollover, the expression accuracy of TOM is rather important. In addition, the difference of the loaded radius of left and right tires yields tire roll angle and that also affects vehicle roll behaviour. In this paper, the modelling of TOM and loaded radius are presented first, and then the modelling results are compared with tire test data.
