speedometer is off by 5 MPH at 60
so, the title pretty well speaks for itself...
when the speedo says 60, im only doing 55. when the speedo says 40, im only doing 38 (according to the signs they put on the sides of the road). the question I have here is this: how can I fix this? the tire is the proper size (I thought that it may be a smaller circumference which would make the speedo off etc, but it is the correct size) since its all electronic etc, I have no clue how to fix the speedo... any ideas?
