I certainly second Steven's notion that new Michelins are great and
that the tires recommended by the manufacturer are the best tires to
use and that if Michelins are in the list they're the best ones in my
experience.  I should add, however, that new tires are always going to
feel better than the old ones just replaced.  Newer rubber, not
hardened with age, deeper tread also equals softer, better ride, etc.,
etc.  It's the "reinforced" vs not reinforced that likely makes the
crosswind difference, however.  I think the only good alternative to
"reinforced" is "C" as the door jamb sticker will indicate.  I just
think, however, there is a fundamental difference between European
tires and American tires, however, with much more compliant sidewalls
usually the case with the latter.  Don't see how American tires can
ever be right for a Vanagon.  I think most Asian tires (available in
USA and relevant to Vanagons) are closer to American than European.
