Speedometer Is Off
I have a 2009 F 150 that the speedo is 3 mph slow. I can not find a section for Windstars, but my 1999 Windstar speedo reads 4 mph slow also. Could they have the same problems?

If the tires are the factory issued size, then I’m not sure there is a problem.
My ‘03 F150 reads a flat 3 MPH high from the factory. Period. Pass by any roadside radar unit and that’s what it reads compared to the speedometer. Factory 255/70/16s on it.
