It's already been said by someone here (Dennis, I think) .... why would
someone
consciously put a wheel (rim) on a vehicle that weighs between 3600 and 5800
pounds, that was designed by engineers to accommodate a 3100 lb. curb-weight
vehicle?

Just my own opinion .... that doesn't even begin to take into consideration
the
side-loading the vanagon endures by environmental considerations, which get
directly translated to rim and tire stresses (cross winds, driving down
mountain
passes through curves and turns "at speed"). The Passat by its design
nature,
cannot begin to endure those same loads.

Sometimes economy and safety are not bed-fellows to be combined.
