An experimental system has been developed to measure the driving forces, side forces and axial torques of driving and braking tires with a side-slip angle, when they are subjected to a known counterforce form the ground. In this system, four wheel driving equipment with its center of gravity at the center of the four wheels is driven at a given drawbar angle until an equilibrium state to determine the component forces mentioned above. In this study, driving and braking experiments were made to block tires for uneven ground on a concrete road, to experimentally validate the principle of the system. As a result, an equilibrium state was realized, in which the component forces were experimentally determined.
