Speedometer calibration ?

[AnastasiaFranco]

FWIW, mine was out by 10%. I've gained 5% of it back by changing to larger wheels and tyres and I'll get the other 5% next time I buy new tyres because I'll buy a larger profile again (since I now know there is room). Read about it here if you wish:

Correction of speedometer through change of rolling ratio

Thanks, I actually saw that mentioned earlier. Tires are good now, so I'll suffer, but when I change them I will move to 17".
