how long can a drive a car with a wheel that has been fixed with "fix a flat"?

you should really only be driving it to the shop, at low speeds. avoid highways.

you can drive on it with no adverse effects as long as there is no wheel balance issues and the leak is sealed. that is what its for use your best judgment your the one driving the car but check for screws and nails in the tread area of the tire if there is then just run it up to your local goodyear and have the tire patched as a plug can pull back out and leave you stranded with a flat at the worst time.... good luck

Just until you can get it to a tire shop. Be sure to warn them it has fix-a-flat in it, because it is nasty stuff when it pours out of a tire.

You can use it as long as you want, as long as You gheck the air in that tire every day, yes every day, cause its going to leak and if you dont keep the air up. the tire may pop at speed

I wouldn't suggest running it for more than 50 miles at a modest speed.
