"Consumer Reports (yeah, but it's the only source I have on this) reports that the real world difference between tires with relatively high RR ratings and relatively low RR ratings is about 1%."
Tire Rack would say otherwise. In the recent issue, page 9, they show more than a 7% difference just on tires. On a Prius, the got 53.8mpg on the Michelin Energy Saver A/S, and 50.0mpg on the Goodyear Assurance ComforTred. Tires do make a big difference, as does tire pressure.
