The bottom of this page tells how to decide which of the three stock tire
sizes was spec'd for your Vanagon:
http://www.vanagon.com/syncros/syncro16/index.htm.  I understand as you do,
Loren, that only vehicles equipped with alloys came with with 205/70R14, and
those vehicles are also equipped with a larger spare tire cover. So, if you
try to cram a 205 in the spare slot on a van made for 185R14s, it should, I
think, seem quite obvious that a fatter tire doesn't fit.
