re:  UniRoyal and is making junk tires in the US with the Michelin
name on them

Need more detail:  seems hard to believe any Michelin tire approved
for a Vanagon (MX or Agilis) would be made in USA.  Volvo experience
is likely not relevant.

re:  Buy only Michelins with the French country code molded in the
tire.

I'd be surprised if Vanagon-spec Michelins are made in France.  My MX
are made in the UK and others could be made in Germany or Spain.
Code?  What code?  Mine say "MADE IN THE UNITED KINGDOM" on the
sidewall and I think I don't need no stinkin' code!

This so-called warning is BS.
