Vehicle pull is one of the most important problem at the initial stage of vehicle development. It is generally known that the vehicle pull is a phenomenon occurred by the residual force and moment. To minimized vehicle pull in this paper introduces the analysis method of vehicle pull simulation which makes it possible to consider matching factors between a vehicle and tires using design of experiments. Therefore, it has analyzed the correlation between factors using ADAMS/CAR S/W including PAC2002 Tire model.

Pattern shape on the tire is one of the most interested area for the tire designer, because it is important component which is related with a lot of performances and also should arouse customer's interest. Especially, the behaviour of tread pattern block is one of basic reference that estimates wear performance, breaking performance, and cornering performance, etc. To estimate this behaviour of pattern block, block stiffness values have often used in the pattern shape design step. In this study, numerical and analytical approach are introduced and compared to estimate block stiffness of pattern, and we study on the method to apply block stiffness to pattern shape design. And by applying this method to simple pattern block, we investigate the relation between block stiffness and tire stiffness by tread pattern.
