Can't advise on fit of tires without knowing their size. Even if the rims have the correct bolt circle, hub diameter, offset, etc, it is highly unlikely that they would be rated for a vehicle as heavy as a vanagon. Miata's are very small and can't weigh much.

Okay guys... sorry for all these posts.
It sounds to me like the Nokian Hakka's are the way to go.  However, well
their advocay by some (like Mark) has been very convincing, my budget
might get the better of me.  I might have the option of getting 4 blizzak
tires on 14 on '94 miata rims for not too much---maybe under a hundred
dollars.  They've been used for one season, and still have a lot of tread
on them.  Sor far, the best deal I've found on Hakka's is $99 a piece.
Should I take these?  So I know (or am guessing) that the rims won't fit
my van, but will my rims take the tires?

Thanks guys,
wes
