This SAE Recommended Practice describes an evaluation procedure for validating tire models for use in road load simulations and assesses the relevant dynamic behavior of tires. The laboratory test utilized is a âcleatâ test, where a rolling tire on a drum encounters a cleat and the resulting dynamic forces and moments are measured. This test is described in SAE J2730, âDynamic Cleat Test with Perpendicular and Inclined Cleatsâ. The test is commonly used to identify tire model parameters. In this recommended practice, requirements for the measurement of the tireâs response are described along with data processing techniques and calculations used to quantitatively compare the tire modelâs calculated response to the tireâs response measured on test. This recommended practice addresses both the tire model structure and its parameters.
