Yet in this particular thread (Peakster's A-B comparison with donuts vs. regular tires on the rear), he found a fairly large efficiency improvement.

Though not knowing the RR characteristics of the regular tires, it's obviously not something one could extrapolate to every vehicle. And methodology is debatable as always.
