I've got an older SAE paper from some of the big-dogs.They did tunnel testing with and without the moving ground floor and results were so close,they deemed the added expense and trouble not worth the effort.The difference in drag associated with the stationary vs. rolling wheels could hardly be discerned from the signal-to-noise ratio at the tunnel floor.
