Have you ever had a flat tire? Where was it and were you able to get it changed or do you use AAA or something? I've had one flat tire while actually on the road. It was while I was driving home one day. I must have hit something sharp because the tire was ruined. I had to put the spare on and take it in and buy a new set of tires for the back. I have one currently as well but it didn't happen while I was driving. Just doesn't keep air in anymore. Annoying.
