[net.auto] Tire ratings

wsh@hou5g.UUCP (11/12/84)

It's new tire time for my Volvo.  What I have found in searching is that
there is a very confusing rating system for tires.  Consumer Reports, some
time ago, reported on a rating system involving letters "A" through "C."
The dealers, on the other hand, have been telling me about the letters
that appear between the numbers (such as the "SR" in 185SR14).  Would
somebody like to illuminate me on this arcana?  Any good advice will also
be welcomed; bad advice will be redirected to /dev/null, using the dwim(1)
utility.
