The ability to predict the performance of wheeled vehicles across country is of paramount importance in both the design of military vehicles and assessing their effectiveness within a specified theatre of operation. In a previous paper by the authors a predictive formula was developed which effected the prediction of the rolling resistance and sinkage of towed wheels on sand. The advantage of the form of the equation was that, where other workers had employed the cone index gradient as a measure of sand strength for mobility studies, this prediction used only the soil bulk unit weight and the angle of friction of the soil. The predictive equation was shown to correlate well with experiments on a wide range of wheel geometries, loads and granular soils.
