I think I may qualify as one of the first to purchase these tires,
having done so four years ago.  Since then, I've racked up 50K miles
without incident.  The wider, lower profile gives the van a nice,
stable feeling.  They are also considerably quieter than the Michelin
185 (XZX?) tires that I had mounted previously.  I could probably put
another 5K or so on the MXT's, but the rear tires are starting to get
close to the wear indicators.  I see no reason to argue with a good
thing, so I'm replacing them with four more of the same.
