I have done it for quite a few miles as long as it isn't coming apart or off the bead and you are not in danger of getting run over you won't hurt anything but as you found out you are in danger of losing control. Never try to reuse a tire that you drove on flat. It causes the cords to seperate.

I learned all I need to know about life by killing smart people and eating their brains.
Eat right ,Exercise ,Stay fit, Die Anyway!
