I believe that
Tirerack breaks out that type of tire on their website. You can certainly just reach out to them through their website and inquire about the current best deals.
I have driven on Goodyear Assurance fuel max and Michelin energy saver A/S tires. Also drove on some Bridgestone Ecopia LRR tires that I can't recall the full name for. The Michelin was the best riding one. The others were ok, but the low rolling resistance types have a pretty big variation in road noise, ride quality and grip. If you have a mostly urban commute, I'm not sure if you would have any benefit from these types. If mostly highway is your situation, the payoff could be significant. Even more so if you get a nice rebate for buying them.
