It is extremely dangerous to drive on a tire which has been damaged by being driven on when it was flat, if this is what you mean by "run flat damage."
If you are present to look at the inside of a tire which has been driven even a relatively short distance without any air in it, you will see that it will have a quantity of black powder in it when it is removed from the wheel.
You might ask where did that powder come from, since it wasn't there when the tire was put on.
Well, that black powder is actually ground up and baked rubber that has come off of the inside of the tire while it was being driven without air pressure. You see, without pressure a tire flexes tremendously as it rolls and this produces heat. The heat weakens the rubber, and as it gets hotter, it bakes it, too.
So if there is any black powder inside the tire ... you are looking at part of the tire which won't be there if you fix the hole and use it again. You are just begging to have a blow-out or tire failure at some critical moment if you use a tire with this kind of damage.
All that being said, if you have a tire that simply went flat when the tire was parked, you take it off and patch the air leak, and there wasn't any other damage to the tire, chances are that it might be safe to use it.
