Here's a bizarre flat tire I witnessed last week:
Front tire, Continental I think, probably 700x23. 3 inch (7.5 cm)
common carpentry nail went into the tire slightly off the center of the
tread, exited tire on sidewall near the rim. So when the rider comes to
a halt, the nail is stuck through the tire in two locations.
I was following the victim when I saw him dismount with this flat, and
quickly caught up. He said "Have you ever seen a flat like this?" and I
had to answer "no."
QUESTION: How the heck can you even *get* a 3" nail in your *front*
wheel? I mean, nails lie *flat* on the road. There wasn't any deep
debris in the road to hold it up. I remember seeing a somewhat similar
flat discussed here a while back, so I know it's not unheard of, but I
don't understand how it can occur.
Sorry I can't remember if the nail had a head or not (e.g. finishing
nail), and I don't know the victim, so I can't ask.
