Correcting spedometer for tire size
Ya'll guys seem to be a little more knowledgeable on the electronic side of the SD's vs some other guys I know, so maybe ya'll can help out.
I have 315 (33") tires on my truck and I have wanted to correct the spedometer ever since I have owned it. I can go 50 miles but my odometer will say 46 miles. Ford dealer here says they can't flash the pcm for the tire size. So is there any way, other than buying a programmer, to correct the spedometer? Thanks for any input
