my scirocco came with a set of hankook snow tires on it when i bought it.
they seemed to last pretty well, never had any experience with the tires
that they make which would fit a vanagon.  i can say that the type of tire
that the vanagon needs a 14" load rated tire is very common in asia, so
they should be a decent tire.  hankooks are korean as far as i know.
