Mark, I don't know what to tell you.  I figure with something as critical as
wheels, I don't take chances.  I use wheels that are made for the vehicle and
not any others.  Just think if you had an accident because of your Passat
rims and hurt or killed someone or just caused alot of damage.  Or even if
your rims didn't cause the problem but your tire just blew.  The insurance
company folks and lawyers would skin you alive for not having Vanagon
specific wheels on the van.  Thats my opinion.

I learned from the aircraft industry that you always need to cover your rear.
