The idea is to measure the tread material elastic recovery to get an idea of the hysteresis loss. But Michelin did a similar demonstration a year or so ago.
They had two large cars, one with low rolling resistance tires and the other without. They set them on identical "U" tracks in neutral and started them rolling. The low rolling tire car stopped last.
