Tire wear. New tires don't exactly match OEM tire diameter that it was calibrated for. Or that fact that most factory speedos are not perfect to begin with.

I saw a test Car and Driver did a while back. One of the biggest offenders of bad speedos was BMW. GM was actually on the good side of average.

Except it wouldn't work. Wearing tires makes your tire diameter smaller, so you move LESS with each revolution, hence slower than you think you might be going. Try saying the tires are non stock and act stupid.

That might actually work, if the flirting doesn't work first.
