What to do when you get a flat tire

First off may I just say, HELP!!! What am I supposed to do with a flat tire on my segway? How am I supposed to make it not flat?

So, for about a month now my friends have been telling my tires looked flat. They did not look flat to me and the segway still worked just fine, until today. Today I had been out for about a half hour when one of my tires randomly went flat. At first I though the sound I heard was just a leaf cauight on a wheel, but then the segway started to act up. A man I passed said, "got a flat tire, huh?" and then I knew, the rumors were true. My segway has a flat tire.

What do you do when your segway randomly gets a flat tire. Well, if you're smart you get off and walk the segway back home. I'm not so smart. I stayed on the segway, made a wrong turn or two, and rode it back to my dorm. I had to go very slowly. Sometimes the segway would randomly slow down. Other times it would lean too far forward or too far back. Some times it started going off to the right as if it wanted to topple over. I stayed on. I prayed. After some difficulties, I got back safely. If this ever happens to you, go no more than 5 miles per hour and keep a constant eye on the key for when the smiley face becomes a frown face (it will do this very frequently).

Anyways, now I have no way to return the DVDs I checked out that are due back Sunday before noon. Everyone is gone for fall break who could take me. What am I supposed to do? How do I make my tire not flat? HELP ME!
