P.S. Fixaflat has never worked for me on any type of puncture, but it did stop a slow leak between the bead and the rim once.

Anything but a full size spare is a joke. When my wife hit a rock in the middle or the road and destroyed the tire and the rim, I was able to find a pair of good tires already on the rims at one local junk yard for less than the the other one was asking for one rim. I put the matched set on the car and used the oddball for the new spare.
