I'm impressed with getting a rolling resistance value for the one 14" tire. I had tried to find the values for the Consumer Reports top rated tires and failed to find any metrics:
- Michelin X Radial (Club Tire)
- Michelin Agility Touring (Sears)
- Michelin Harmony
- Toyo 800 Ultra
- Sumitomo HTR T4
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.
Thanks,
