I don't think that is exactly true. Most sticky performance tires have low treadwear ratings, and also high rolling resistance. My current tires have a rating of 420, and they don't seem to have low rolling resistance.
Found a Prius driver's comparison between the OE Goodyear Integrity, BFG Touring T/A Pro, and the Yokohamas I'm looking at, the Touring S.

The reviewer says the Yokos got him 1 MPG more than the OE Integritys, which are listed as LRR tires. Looks like I found my new rubbers.
Now the question of sidewall stiffness remains. I'm very tempted to go with the 195 wide, since the load rating for those is 90, and the 185 wide has an 87 rating. My current ones are 88 and feel a bit squishy in turns and sluggish to respond to steering imput. I'll most likely be going with the 195s unless I find that having the softer sidewall will net me at least 2 MPGs more. I'm willing to make a small tradeoff to have a better handling tire.
