Subject: RE: Speaking of tires...

I did a bunch of research a while back to understand what the tire
size/shape letters/number mumbo-jumbo was all about. I put together some
of my findings on my website, in case you are interested. I find I have
to reference it myself whenever I want to be sure about something.
