I am just glad that the tire was already flat, had it been full of air and let go, it probably would have taken out the other tire and made for a nasty situation. by the time we realized what had happened, the trie was at a point that it wasn't a big safety hazard and I took the risk, since it was so old, the sidewall was stuck to the rim like it was welded and that helped the situation a lot. Was it the safest thing to do? Probably not, but there were very few cars on the road, and we were monitoring the situation close enough that I felt like it was the best solution. With no spare, we wouldn't have gotten any roadside help, at least not quickly. I wish I had taken the time to get a spare myself, but when the seller tells you he has four spares for you, I guess you just think you will be fine, live and learn.
