This paper presents a computerized tyre pressure control system for off-road vehicles to achieve the required tyre flotation pressure during their mobility. This method accounts for soil deformation and tyre deflection in the vehicle tyre-terrain interaction. A test rig has been designed to apply vertical load to the tyre at the tyre to terrain surface. The deflection and inflation pressure of the tyre were recorded by a data acquisition system. The test rig is integrated with a pressure system for tyre inflation and deflation. The proposed control system ensures that the soil deformation is higher than the tyre deflection. Experimental results showed that the proposed control system adjusted the tyre pressure to the flotation pressure for a given load and soil conditions within a reasonably shorter elapsed time.
