    It is obvious that if you give priority to comfort and tracking, you
    should prefer af 25 mm to a 23 mm.

    And why not 28 mm to 25 mm while you're at it...

    But even if you give priority to speed, the 25 mm tire appears to be the
    better choice. But nobody knows.

    I don't think anybody has questioned the fact that the higher the
    pressure, the lower the rolling resistance. Narrower tyres can handle
    higher pressures while causing less stress for the rim. If you want
    pressures higher than what 25 mm tyres can take you must use a narrower
    tyre.

    I always pump my 23 mm tyres pretty hard. 9 bar in the rear and 8 in
    the front feel pretty good. As a lightweight rider (70 kg including the
    bike) I absolutely don't need such high pressures, but then it doesn't
    bother me at all and I can ride my usual mileage without any discomfort.
    Even if the increase in rolling resistance might be very small, it
    doesn't seem like a bad deal to me.

    Depending on the smoothness of the road, you might actually be increasing
    your rolling resistance by pumping that high.

    Correct, and I'm sure on some roads that is the case. But typically the
    roads here are pretty smooth and I'm sure on average the rolling
    resistance is lower.

    It could well be. It's too bad there aren't more test results available for
    this. For me, 7-7.5 bar feels pretty good, for bike+rider of about 80 kg.
