The present invention is directed to a system and method for simulating the interaction of a simulated vehicle with one or more simulated road surfaces. A computer modelling program is used to create a computer-based road surface model and a computer-based vehicle model. The computer-based vehicle model may include a body model, a chassis model, a suspension model, a wheel model and a tire model. A computer simulation engine program is operative with the computer-based road surface and vehicle models to selectively simulate the interaction therebetween and provide simulation data relative thereto. The simulation data may be used to identify high stress areas or low durability areas of the vehicle or to compute vehicle suspension parameters.
