A vehicle dynamic simulation is conducted in this paper to study the effects of tire performance on the handling stability of vehicle. Firstly tire mechanical performance test is performed on three set of tires, and with the force and moment data obtained from test, a Unitire tire model is built. Then a vehicle dynamics model is set up, a simulation is carried out with CarSim and the model is verified by test. Finally with the verified vehicle model, steady state circular test, steering wheel angle step input test and double lane change test are proceeded, with test results analyzed and the effects of tire performance on the handling stability of vehicle objectively evalua-ted.
