Almost always, the rank ordering of tires on rollers is the same as on the road. Sometimes two tires will swap ranking, but usually that's when the tires are pretty close to begin with. An exception can occur when the impedance break point on one tire comes a little earlier than the other. If you're in the neighborhood of that threshold, you can also observe a ranking swap.

Almost always, if you see a discussion of impedance breakpoint they're talking about real world field testing on roads as opposed to on a roller.
