Scary. Life lesson. Stuff like that never leaves the back of your mind. (Not tire related but still) I still think about the the time I was trying to get my oil pan off with the motor still in the car. It just would not clear the cross member so I loosened one side motor mount and, while I was under the car, had my wife pulling on a big 2x4 trying to lift the engine enough that I could pull it free. When I look over at the jack stands and they are teetering over as I tell her to pull. Just one of those stupid things that make you shiver a little bit when you think about it. Lesson learned.
