It's not ideal, but if I'm on the side of the road I rarely have good options. The old story was the tire would explode in the shop. Not anymore. But it still forms a paste that damages the tire. Not sure who to believe, some FAQ:

Is there a brand that does not harm the tire?

I've never heard that it damages the tire per se, but "FIX A FLAT" products should be thoroughly cleaned off the inside of the tire to apply a patch. In early TPMS days the fear was that it may screw up the TPMS (if applicable) so that may have to be replaced. Not sure that applies with the new generation of TPMS.

Of coarse if you're stuck on the side of the road in BFE without tools, tire plugs, etc none of that may concern you at the time.

Yeah, years ago when I worked in the tire shop we would just clean out the fix a flat liquid and put on a patch. No problems.

I don't know if somehow plugs don't work as good. But I'll also say you can get a tire plug kit and a small compressor for the car and plug a tire if you can find the leak. That's a permanent fix usually. But it can be a bitch to do if the tire is on the car.

I’ve used Fix-a-Flat for years. I get a puncture, nail or something, I just put in some fix a flat and ride it till I need new tires anyway.
Works like charm and I’ve literally gone for a couple years on a fix-a-flat fix.

You should buy lottery tickets because that's luck, not because of the quality of the product.

There are nails and other things that cause flats all over the roads following hurricanes. We kept cases of that stuff in emergency supplies for use in our cruisers after hurricanes. I don't know the long term effects but it sure kept our cruisers moving in the short term.
