Perhaps MAXPOWER would know. I have a 95 Dodge Intrepid and due
to changing tire sizes from the original P205/70R15 to
P215/65R15, the speedometer reads 10 pct. fast; i.e, at an
indicated 65, the car is really going about 58mph. I have to
keep doing the math in my head to estimate my REAL speed.
Granted, this is keeping me away from being stopped by the State
Troopers, but is there a way to flash the computer that runs the
speedometer, to correct this speedometer error?
