It's not easy to get rolling resistance info about a tire. If you're considering low rolling resistance tires, you should read TireRack.com's tests of several LRR tires on a Gen II Prius: When Round and Black Becomes Lean and Green Also check out Consumer Reports November 2009 tire tests (key in on those tires with the best rolling resistance ratings): Consumer_Reports_Nov._2009_Tire_Tests-1.doc
I just picked up a set of 195/55/R16 Michelin Energy Savers for my '08 touring grade and they are awesome! Much QUIETER than the OE Bridgestones and my MPG's have improved by 6%. I purchased the tires from my local Costco, and the tire purchase experience was terrific. They gave me a great price, quick service, and road hazard warranty.
I have a 2004 purchased in Oct 2003. I was told it was the 4th sold in the state. I put Michelin HydroEdge on the car a few years ago and it KILLED my mileage. I'm checking on choices for when I have to replace them. Thanks for your input. Sounds like the Energy Savers A/S are the ones.
On the Gen II Touring, I would expect about a 6% improvement with the Energy Savers over the OEM Bridgestone Turanzas El-400 V speed rated tires. With some wear, I think you'll be seeing even more improvement. On the Gen II Standard Prius, TireRack got a 4.74% improvement with the Energy Savers over the OEM Goodyear Integrities. I wonder how well the Energy Savers will perform in snow and ice (TireRack didn't test the tires in snow and ice.) When Round and Black Becomes Lean and Green .
They now have HydroEdge with GreenX. I guess that means they put those LRR compound in HydroEdge. I wonder if it will get better MPG than the original HydroEdge.
I bet HE with Green X gets better mpg than the original HE. But did you notice that in the TireRack tests, the HE with Green X got a tiny bit worse mpg than the OEM Integrities?
Does anyone know if the cooper GFE (GREATER FUEL EFFICIENCY) LRR tires will give you better MPG than the stock Goodyear Integrity tires? They came out a few months ago & been looking for that info but can't seem to find it.
Ya, MPG and dry surface performance is almost as good as OEM and perform way better in wet surface (where OEM is weak at). Cheaper and more tread than Energy Saver. I think it is a very good balance.
I don't know what others think but I bought the Michelin Energy Savers. I can tell a difference (better handling & mileage) but I don't have hard data to prove hit. There is one stretch of a two lane surface road that I travel frequently and I noticed that I have 2 extra bars of battery power when I reach a traffic light as compared to the factory Goodyears. I don't believe I am driving more efficient than before so I believe it's the tires. I'm impressed with the tires.
Here is the proof but we don't know the other tire they compared with. [ame=http://www.youtube.com/watch?v=B-1VIkjj_lk]YouTube - IAA 2007 - Michelin Energy Saver[/ame]
