Several years ago while on tour I woke up to a flat tire. The leak was so small I had to run the tube through a convenient puddle to find the puncture. Once I did I matched it up with the tire but still couldn’t feel anything until I turned the tire inside out. That’s how I found the piece of wire. It was maybe 1/8 of an inch long.
I had one of those last year. I could feel it on the inside of the tire, and JUST see it, barely, but I don't wear my glasses to ride, and I had a hell of a time trying to grab hold of it with my fingernails and pull it out, by the side of the road.
