 This is ambiguous. What do you mean?
 Do you mean that if I am travelling at 70 my speedo reads 66, or if I am
 travelling at 66 my speedo reads 70?
 Does this also apply to Vanaogons with the 6" alloy stock wheels?

If your speedo is showing an INDICATED 70 MPH,  your TRUE speed is 66 MPH.
Time your, van and see for yourself. All cars show more than your are really
traveling.  This is true also for my 99 Passat and the rest of all my Vw's
that I've owned. Every car I drive, I time check the Speedo.   Was checking
out a friend of mines new Suburban and guess what? An indicated 75 was really
71 mph true speed.  See ya, Michael.
