An empirical methodology is described for separately characterizing vehicles and road courses for subsequent combination to predict tire force histories in tire use or testing. A major requirement for indoor simulation of outdoor wear testing is that the indoor tire force histories properly represent the actual outdoor force conditions. An efficient laboratory method has been developed for experimental vehicle characterization. The laboratory features two in-ground force and moment measurement platforms for conducting 'drive by' experiments. Laser based inclinometers are used to measure wheel inclination angels during the laboratory experiments. A vehicle can be fully characterized by this TS-SIM method in one day, or less, of laboratory testing. The characterization techniques can be employed with actual vehicles or dynamic models of vehicle prototypes. The TS-SIM method was validated with several experimental and computational models. The authors describe lab validation, outdoor validation and validation with a vehicle dynamic computer simulation model. The following examples of applications are described: Heel/Toe simulation; Outside shoulder and centre wear simulation; Simulation of uneven wear; Simulation of 'Wear Out' projection.
