speedometer and odometer incorrect
my speedometer reads about 5 miles over when going about 30mph and
even higher difference at higher speeds. my odometer is picking up miles
crazy fast about 7x what i am actually going.
If you have changed wheel/tire size from stock will effect speedometer and odometer Remember if you are watching a trip odometer that shows tenths of miles and the total mileage odo does not.
thx your right first car didn't know it was tenths. i feel stupid now in my defense it doesn't have decimals on mine.
That's why we are here... don't feel stupid. Happens to all of us.
