A tire traveling test device has a belt that horizontally spans between two drums and a load support device that supports a flat surface of the belt from a lower surface side of the belt. The apparatus includes a pump operable in discrete cycles, a power source connected to the pump, and a controller connected to at least one of the pump and the power source. The one or more multi-faced dice are configured to generate at least one random number. In an embodiment, a pressure switch provides input to a motor controlling the pump. The user may then instruct the software to mimic the communications of the IED by returning the recorded responses when given the corresponding command. As a result, the elastic projections projecting from an outer peripheral line of the hard base can be elastically deformed so as to retract inside the hard base.
