The Michelin Primacy is rated a 10 out of 10 for fuel efficiency on the . Michelin website and rated extremely high on Tirerack, but is not available in the size required for my Civic.
Let's talk about the tires you like to use on you car to increase mpg.

The problem with the reviews is that there is a technology triangle involving treadwear, traction and rolling resistance. To get good results in one area, one (or both) of the other areas has to be sacrificed.
Many people take off their OE tires (Original Equipment tires - the tires put on at the vehicle assembly plant, like the Primacy) which give pretty good fuel economy, but have wear and/or traction issues and replace them with better wearing tires (or better traction tires). They will experience a loss in fuel economy - and that's what they are reporting.
