Fortunately there are a lot of new tires available that have been designed for low rolling resistance.
The Potenza RE92's are only LRR in the 165/65/14 size. That's a pretty limited option and would require considerably taller final gears to make up for the reduced diameter and you would definitely want to add skirts to the wheel openings to close the gap as much as possible.
I use 205/70/15 LRR Goodyear Assurance Fuel Max on my diesel Maxima and there are several other LRR brands in that size.
It would probably improve my Cd by going down to the 165/65/14... I have a spare set of 14x5.5 wheels for the Maxima but they may be too wide for a 165... hmmm...
