The rim-rolling test is a fatigue test that allows to evaluate the resistance of the wheel during rolling under a load condition, as it occurs on a road drive. The wheel is mounted on a wide diameter-rotating roll simulating the road. It is possible to apply both radial and lateral loads in order to reproduce the vehicle weight and the steer conditions. It is possible to exploit this test to evaluate the resistance of other surrounding component like hubs and brakes.
