Thanks to all who advised me concerning tire chains for my 1991 Volkswagen
Vanagon GL Campmobile.

Even though I now had not only the tire size, but the product number (thank
you Roger), when I went back to Les Schwab, they still tried to insist that
the size they sold me first was the one I needed, because that's what their
computer said.  I pointed out that the product number I was requesting came
from LaClede, and that I had called before I came in to check to make sure
they had what I needed.  Still, "but that's the wrong size."

Finally, a supervisor, overhearing, told the person "helping" me to fit the
chain to my tire.  Of course, it would not fit.  Then he got the one I'd
asked for, which said right on the label "195R14," along with some other
sizes. It fit.

So, I got the chains I need, but not without some interference from the
seller.  Good grief!
