 I'm out running errands. I come back. I park the car outside the house because I'm leaving that night to go on a trip. I'm in the house getting ready and there is an explosion. It is so loud. It sounds like kids dropped M80s in the sewer. We live on a cul-de-sac. It brought everybody out of their door. What is going on out here? It turns out that the tire, two hours after I drove, the tire just exploded.
