The time-domain simulation of tire lateral deflection characteristics is an important part of tire dynamic characteristics. The model can be used to test and simulate the dynamic characteristics of tires and vehicles. Based on the tire lateral unsteady model established by the experimental modal parameters, the time domain transient response formula for calculating different lateral inputs is derived. The time-domain response of the tire under lateral displacement and wobble angle input is calculated. The calculated results are in good agreement with the test results of the same tire, indicating that the model is successful. Derivation and calculation results improve the dynamic model established, and further illustrate the use of experimental modal parameters can be in-depth and convenient to establish the tire mechanics model
