Have you ever gotten a flat while riding? I have, and it's not a lot of fun when you tip it into a corner and the rear tire tries to pass the front. I don't know about you, but I won't chance hitting the deck over a tire that won't hold air, especially if I know ahead of time that the tire is suspect. We can file that one under "stupid hurts".
