The tires reviewed were:
Bridgestone Ecopia EP100
Goodyear Assurance ComforTred
Goodyear Assurance Fuel Max
Goodyear Integrity
Michelin Energy Saver A/S
Michelin HydroEdge with Green X
Yokohama dB Super E-Spec

The article is at:
When Round and Black Becomes Lean and Green

Yes, great new TireRack article and test -- testing tires that a lot of PriusChatters get or are considering, and testing them on a Gen II Prius! Doesn't get much more relevant than that.

Note that there's a new lower rolling resistance formulation for the old Michelin HydroEdge called the Michelin HydroEdge with Green X.

FYI, someone else started a thread today on this new TireRack article:

Tire Rack pits Integrity against Energy Saver, Ecopia and Fuel Max

Below is a summary of the MPG results from the test and article (but one should read the article for, among other things, braking and handling results):

"Tire LineTest MPG*% vs. O.E.

Michelin Energy Saver A/S: 53.8 MPG +4.74%

Bridgestone Ecopia EP100: 53.5 MPG +4.12%

Yokohama dB Super E-Spec: 52.8 MPG +2.81%

Goodyear Assurance Fuel Max: 51.6 MPG +0.37%

Goodyear Integrity (O.E.): 51.4 MPG --

Michelin HydroEdge with Green X: 51.1 MPG -0.59%

Goodyear Assurance ComforTred: 50.0 MPG -2.64%

*Calculated based on GPS distances and ScanGage II recorded consumption (offset 6% for Prius Summer E10 regular grade fuel)."

I have had both on my car and I recommend the TripleTreds. The michelins wore out at 65k and made ungodly noise on the highway along with shaking in the steering wheel as the miles racked up on them. Yes, I did rotate them. I have had the TripleTreds for 56k now and they are wearing much better than the Hydroedge. I have noticed a much improved ride with either tire over the Integrity garbage tire, at least initially with the Michelin....Good Luck!

I've been getting 57 MPG or so all summer long on my Triple treds. When I still had the Integrities last summer I was getting 60 MPG all summer, but this year we had al lot more rain.

Triple Treds are also made in the USA if that is of any concern to you.

I have been unable to find any tire dealer that would put "T" speed rated tires, like the Hydo Edge, on my Prius with it "V" rated OEM Bridgestone Teranza tires. The lowest they will go is with a "H" rated tire like the Goodyear ComforTred.

You could buy tires from TireRack.com (or other online vendor) and have them drop-shipped to one of their approved local tire installers. The local tire installers are not going to care what tire it is -- at that point, they're only interested in installing what you shipped or gave to them and collecting their $15-25 per tire installation fee.
