The tire model presented in this paper covers almost all operating conditions developed by complex motion of a vehicle. The features of the model includes: - longitudinal force, lateral force and aligning moment are generated simultaneously according to the non-steady longitudinal slip ratio, slip angle as well as turn-slip. - Non-linear tire characteristics are produced by transient effective slip ratios of tread in both directions, conformed with the unified relaxation lengths according to the instant local slip stiffness. - Camber effects on longitudinal force, lateral force, aligning moment and overturning moment are included. - Effects of dynamic variation of vertical load on shear forces are described through the quasi-relaxation effect of some structural factors, and different filtering effect for the loading and unloading processes. - Effect of longitudinal force on lateral slip stiffness is reasonably described through analytical relationship. - Non-dimensional modelling and independent expressions of longitudinal adhesion coefficient and lateral adhesion coefficient in the model presents the possibilities to study the effects of adhesion properties on vehicle dynamics. - Autonomous satisfaction of boundary conditions at both initial and final states ensures the modelling accuracy over the whole operation range.
