A new semiempirical approach was attempted to predict the slope- climbing capability of wheels. The approach consisted of determining the pull performance of flexible wheels on yielding slopes by two extrapolations one starting from the theoretically known pull performance of flexible wheels on unyielding slopes, and the other from experimentally determined performance of rigid wheels on yielding, level ground. The result is a prediction equation for the available pull of elastic-rim wheels as a particularly simple case of pneumatic tires on deformable, inclined soils in terms of soil deformability, cohesion, and internal friction wheel flexibility and load and slope angle.
