Brian, the Y370 tires you listed are OK.  They are the same tire, 
maybe a slightly different tread pattern.  The important thing to 
notice is that they are of the "LT195/75 R14" variety.  These tires 
all have the 1710 lbs @ 65 psi load carrying capacity with Load Range 
D.  I have Y370B tires on my van.  I've had these for about 3 years 
now.  The LT tires are NOT available in white wall.  These tires all 
carry the M & S designation as well.  Hope this clarifies.
