No, it will not have any effect on them. But it IS a temporary fix just to get you to a repair facility to properly repair the tire (and clean out the fix-a-flat liquid).
agree'dyou can get a tire plug kit from wal-mart for roughly the same price as fix-a-flat...if you can't jam a piece of gooey rubber into a hole in your tire then you shouldn't be putting fix-a-flat in it either.
No nail in tire. It just has a super slow leak. Discount tire didnt find anything.Fix a flat will eat the clear coat off the inside of the tire if you run that stuff for too long..
either that or plug it..
nail in the tire?
