    I actually found that my tires lasted longer (70k) on my first set when I had them at 45. My 2nd set only lasted 60k miles at 40. Could it have been any number of factors? Sure. :D

    Oh wow oldie but goodies question.
    Back in the day, there was a fellow Wayne Gerdes who was the champion of the high pressure.
    He could probably answer that if he is still around.

    Obviously it is convenient to stick with the same revolutions so the speedometer works. And then I think Wayne would still fill that tire up to 50.

    Tires have multiple layers of steel belts to keep the surface that grips the road flat... The archaic notion that too much air pressure will bend these belts and surface will no longer be flat and cause uneven tread wear is entirely false.

    NOPE. Not if it is true economy you are looking for.
    The price difference between E10 regular and E0 (usually) premium, often MORE than makes up for the 3% or less gain in fuel mileage.

    Not entirely.

    Within reason, maybe, but not if you are talking about the difference between a recommended 30 and an actual 50......which might go up to 60 or more when HOT.

    And your broad generalization that all tire designs work exactly the same way is equally (or more) archaic.

    I'm ok with the price breaking even, if it means the lobbyists gotta tighten their belts.

    If I put a resistor inline the gen3 narrowband upstream sensor of a Prius would it trick the car to run lean or rich

    It likely would "trick" it to run BAD or not at all.
    Forget it.

    I find if I don't run my AC in auto mode I get about 5 mpg better
