Abstract: An extension of a previous study on sand, this report summarizes the test results obtained on clay with an experimental wheel with controlled circumferential rigidity. The test program was carried out for the sake of completeness despite the fact that the underlying principle of the experimental wheel was based upon sand properties and, therefore, similar wheel performance variations as a function of tire rigidity distribution were not to be expected on clay. In addition, insufficient torque capacity of the wheel-drive system prevented the performance criteria used in the sand study from being applied in this study on clay. The relation of pull/load to efficiency was the only feasible relation that could be used in this investigation. As expected, no noticeable change in tire behavior could be observed for rigidity pattern variations. Control of tire rigidity distribution at the interface is not effective in clay. Although this conclusion is negative, it confirms the earlier findings on the improvement of performance of the wheel with controlled circumferential rigidity in sand.
