But jj, you are more apt to suffer from a blowout from a tube tire than a tubless one. Like I said, I've taken plenty of nails on my Speedmaster, but none of them resulted in a flat tire. They all held air until I could get the tire changed as long as I didn't mess with the nail by trying to pull it out. And we're talking everything from long staples that carpenters shoot out of their nail guns, to 16d nails.
