A flat tire is a show stopper. You could just drive on but you know in your heart that this course of action has expensive consequences. So here is whatcha do. Go to auto zone and get one of these tire plug kits. I have used these little darlings to plug holes on at least five occasions sometimes right by the side of the road. They work like a charm for any round hole less that a quarter of an inch which in the case of all my flat tires save one was exactly what I encountered. It typically is a stray screw or nail and if the leak is slow, which is also typical, you simply whip out the plug punch, thread the sticky rubber soaked string and plunge it into the hole you have just revealed by yanking out the offending screw or nail. If you caught it in time you have plenty of air to get you to a gas station and an air compressor. After that just drive on with no further worry. I had one tire with two separate plugs in two separate holes and it lasted the remaining life of the tire with no ill effects! I love an outrageously cheap solution. Sometimes the simplest low tech solutions are the very best.
