Lots of Vanagons and certainly most 1990 models came with 205/70/14
tires as the OEM size.
195/75/14 ties are TALLER than this other stock size. So they are taller
than one of the stock sizes and shorter than the other. That makes them
a reasonable alternative to either, IMHO. Assuming you find some with
correct weight rating of course.

That Miata program is far from accurate and only useful to see relative
changes, not explicit values.
Also it assumes the stock tires give a 100% correct speedometer reading
and this is usually not the case. Since there were two different sized
tires fitted to 1990 2wd vans and only one speedometer used it is
apparent on the face of it that the speedo can't be assumed 100%
accurate to begin with. A change in tire size may make the speedo MORE
accurate while the Miata program assumes it would always be less so.
