Take the tour ×  I had a flat tire and replaced the tube. I just
didn't realize that the tube was a thorn-proof tube when I
bought it. It was the only spare one I had, so I used it anyway.
Just now I replaced it with a regular tube. I figure I can keep
this thorn proof one around just in case I get another flat.
The problem is, I can't get all the air out of the thorn proof
tube to store it in the closet. It's schrader valve. I push the
pin in and air comes out, but there is still a lot in there. I'm
trying to fold it up like a tube of toothpaste while pushing the
pin, and it's not working so well. I could cut it and patch it,
but then I may as well throw it out and buy a new tube. Is there
maybe some way to get my bike pump to work in reverse or
otherwise completely deflate this thing?  share|improve this
question I've seen anti-flat motorcycle tubes with double air
chamber, so that when the outer chamber got flat, the inner one
would keep some air to keep it rolling. Would this tube be that
type? –  helton
