I posted a little after my first note that I have measured my odometer error (yes I'm running 185/75-14 tires) as 2%. Are they really 6% smaller? That's a lot. Even if they were, though, that would bring a 65mph measure down to 61.1, not 57.

My real question is whether I should replace the cable or tear apart the speedometer.....
