In order to study the vehicle motion response under the condition of high speed puncture when turning, Based on the Chery QQ car, made a turn driving road test, Using the multivariate regression principle and with the aid of SPSS software, the regression equation is established that among the most sensitive and second sensitive driving stability parameters with tire pressure and speed on the basis of the statistical analysis of data, and the feasibility of the model is verified based on this model predict the vehicle motion response under the condition of high speed flat tire, It turned out that when the speed of 120km/h, lateral acceleration of the most sensitive parameter can reach to 7.868 (m•s-2) at the inside wheel puncture, but maximum roll angle of the most sensitive parameters can reach to -3.590(°), The inside wheel flat tire makes trend of steering yaw heavily, which can bring drift and slip. The outside wheel puncture is benefit to driving straight but there will be rollover. Moreover, according to our research, we know that the inside of front wheel flat tire is the most dangerous situations.
