I have had no luck finding rolling resistance values at Tire Rack and as for other sources, it has been a mixed bag. It is as if rolling resistance is being hidden.
Could you point me at where I might find the rolling resistance values for the Consumer Reports tires?
I recently measured my Prius Crr at 0.0102, which includes the transaxle drag. I'm not really happy with having to buy sets of tires to find the lowest rolling resistance tires.
I had been following the California Air Resources effort to measure tire rolling resistance but got the impression that it 'ran out of steam' last summer. I never saw their report much less some evidence of a continuing effort.

I have Michelin Harmony tires on my Mazda and Michelin MXV4 tires on my Mercedes. Both of them seem to offer good rolling resistance. I could feel an improvement in terms of coasting when I replaced some cheap-o tires with Harmonies on the Mazda.
