A need for speed?
by paulrhein on Thu Nov 05, 2009 6:27 am
I have notice that my speedometer is off about 10%. When my speedo reads 55mph; I am actually doing 50mph or less. Is there any way to calibrate the speedo so it and the OBC read the same? BTW my OBC seems to display the correct mph.

Changing alloys can contribute to false speed readings on the speedo.
Heres a handy little chart

enter original tyre size and then new tyre size and will give you the percentage it will be out and will give you an example of speeds.
