I saw the Consumer Reports report in late 2006. It rated rolling resistance the same way that it rates everything else, with the red dot / black dot system. There were no actual LRR numbers. At the top of the list in 2006 was the Michelin Energy MXV and just under that was the Michelin Harmony. I bought the Kumho A/S 795's for the Prius which ranked just below the Michelins, but were 1/2 to 1/4 of the price. The sidewall max is 35 PPSI but I have been running them at 50-55 PSI. 40k miles so far and easily another 40k in them.
Hopefully the 2007 report had actual LRR values in it. If so, I would go to the library to see it.
