Abstrakt: The tire model validity factors are listed and discussed when using tires in complex multi-mass vehicle models. Complex vehicle system models are used to estimate (to forecast) their handling and stability properties (including Electronic Stability Control (ESC) performance). It should be as less as possible discrepancy between vehicle virtual computational and experimental tests results. The objective forces to create more complex vehicle models. A tire is known to be the one of the most significant elements in the model and to influence considerably on vehicle handling and stability factors transmitting all road reactions. The paper describes factors to be able to get influence on the PAC2002 pneumatic tire model validity when simulating it in MSC.ADAMS/Car Software. The tire model creating begins by conducting studies of rolling tire characteristics. The studies are examined on tire benches. Conducting experimental studies there are the set of factors to be able to bring a measurement error into study results. The analysis of various literary sources has permitted to choose three basic factors to be able to get influenced on tire model and all the vehicle model validity. Among these factors there are following: tire pressure, tire temperature и tire tread wear. The most significant of these factors is the tire pressure. For providing required study accuracy it needs to apply tight restrictions on each factor changing range influencing on rolling tire characteristics. The ranges are to be determined for each certain tire model by using study results.
