But where the big improvement in fuel economy lay is in the difference between tire lines - and, No!, I'm not referring to differences in brand,. I'm referring to a line of tire that comes in different sizes, but the entire line of tires is essentially the same.
But you didn't tell us what you think is important to you in a tire? Is treadwear important? How about traction? What is the balance between these 2 properties and RR?
Tires are compromises and you can't get everything in one package.

Treadwear and LRR is like I care about. I don't need handling as I don't race my car. 85% of commute is freeway, 14.5% is Highway and .5% is city. I don't drive crazy, ever, so I don't need insane handling.
