Abstract: The physical parameters are defined which represent the deformation characteristics of carcass and the pressure distribution ones of contact print. The theoretical model of steady state tire cornering properties is established with the complex deformation of carcass under consideration. The model is validated by test data. Many kinds of simplified theoretical models can be derived directly according to this models and the cornering properties can also be calculated with it when the critical adhesive Point occurs in the opposite ends of contact print.
