Are these Michelin XCA 205/75r-14's even still available? tire Rack
doesn't show them, I don't think.
Is there any big reason to not use this size? I realize they are a 1/2"
bigger in diameter. The load rating on many tires in this size as
120-150lb. more per tire than either 205/70 or 185/80. Is there a down side?
Also, many of these tires are rated anywhere from 36 to 60 psi maximum
air pressure? Are the load ratings AT the max inflation pressure? If
that is the case, would the 36psi tire at 36psi actually carry more
than the XCA or Yoko 356 at 55psi?
Has anyone seen Avon "Van" tires for sale anywhere? Of the 30 or so
mounted Vanagon tires I have here at home they are the only set that has
experienced NOT ONE carcass/ belt failure! Yeah, yeah, I know I
shouldn't put 3000 lb. in my Vanagon, but sometimes...... At lest it's
just the diesel, so no one can accuse me of being overloaded AND speeding!
