Maybe, maybe not. The dyno machines used by the tire companies use for rolling resistance measurement have very large rollers to minimize the divergence from a flat road. This dyno has fairly small rollers.
In addition, my friend runs his shop FOR PROFIT. I'm not going to ask him to spend an hour or more on some sophisticated test I dream up. He is doing the tests because it is simple and quick. My objectives are much more limited.
