Few things are worse than getting a flat tire, putting on that anemic little
spare tire, and then having the spare tire last for just a few miles before
shredding and becoming a motorized pizza cutter.  Unfortunately for me, that
just happened.

So now I need a new spare tire.  One option would be to just locate a proper
rim and buy a tire for it, but storage space for a spare is at a premium
(this is on a 1997 Saturn SL2, the spare tire well is pretty much only big
enough for the standard crapmatic spare tire).  Short of going to the dealer,
where would I locate one of those emergency spares?  I'd prefer to avoid a
junkyard.  The tire repair store didn't carry them, I didn't see one in
the J.C. Whitney catalog, and I don't think I'll have much luck hitting the
standard array of chain auto parts stores (Autozone, Pep Boys, Napa, etc.)
although I'll give it a shot anyhow.  Any ideas or suggestions?
