Some info you might be able to use: My car came standard with Michelin Energy MXV4 Plus tires. I just changed tires (after 63,000 mi., good tread remaining). I bought a competing brand, got bad mileage and returned them. I called Michelin, talked to an engineer. He recommended the following for best mileage: MXV4 S8. (These are new.) These tires are D### expensive. I see that they are supplied standard on the new Accord hybrid.
Well, I got a set. I think my mileage has increased about 2 mpg above the previous Michelin Energy tires.
