>> FIX-A-FLAT WARNING <<
This is not so much a tip about what to do, but a tip about what NOT TO DO.
I have seen this daily for years; people bring in various tires for repair that are sloshing full of "Fix-a-Flat".
If I were stranded in the desert with a flat tire and a case of the stuff, I would probably just drive out on the flat and leave the flat-fixer for the buzzards.
If it stays inside a tire/wheel for more than just a few days, or is not completely washed/rinsed out within the first few hours of installation, it will badly corrode the wheel; steel or aluminum, it eats both.
It does something negative to the rubber such that a proper repair will no longer adhere to it, regardless of how much cleaning and preparation is done prior to attempting to patch the tire.
To an un-suspecting tire-monkey, it will spray him in the eye when he inflates the tire to find the problem.
It will also come splattering out in his face when he breaks the beads loose with the changer.
On another tire subject, I read of many who have "ran a tire off the rim".
In most cases, when a tire is run flat and rolls off the rim, it breaks the wire cable within the beads.
This may not be evident to the un-trained eye, especially to the one that just paid big money for the tire and is not wanting to see that it is now a junk tire.
In any case, the ability of the tire to hold itself together under air pressure has been compromised; and, it can and sooner or later will blow off the rim again with death or maiming being highly possible.
Also, in most run flat situations, the "roundness" of the rim will be compromised, thus making the inflated tire/rim a potential bomb just waiting to blow up in someone's face.
If a tire came off the rim and does so again later, consider yourself lucky no one was killed, slash the sidewall and throw that tire away.
