How sweet would it be to ride through a patch of glass and not worry about a flat? There are many sharp objects that can ruin a good ride in the streets of NYC. It is always a bummer when I realize a sharp object has stabbed through my tire and punctured my tube. But what if you had a tube that could take a sharp object in and allow you to keep riding?
Reader Gray contacted us and has an interesting story about a bike he bought with tires meant to be puncture resistant. All text and pictures credited to Gray.

I recently bought an old road bike and found that the vale stems were missing yet the tires seemed to be inflated; on closer inspection the previous owner had somehow stuffed nearly solid rubber tubing inside. The ride was a bit soft thus I removed the rear, so far the only one I was able to get out, I do feel that you would never need to replace it until the tire wore out.
However that is where the problem may come in; the difficulty of changing a worn out tire and getting it back on. I feel that I may need to cut off the front tire when it does come time but only time will tell.
#1- This shows that the tires were fit 'professionally' with a puncture proof material.
#2- Here is the puncture proof tubing; it amounts to a thick rubber tube of approximately 4 inches around but really it would depend on the tire size that you would like to fit it to this came off a 26" and 1 3/8 wheel.
#3- Shows that the tubing is hollow and does give some when one is on the bike. I tired to puncture it just to see how tough the stuff was and I was unable to stab anything I had through it.
#4- Just insert the tubing into tire and do as you would a normal inner tube; no worries about pinches or being careful and you will need to force it on with all your might as well as any levers you have handy.
A word of caution is that it is very difficult to get the tubing in and on the rim you have no space to spare as you do when you deflate a tube as likewise when trying to change tires it is nearly impossible to remove because the tubing takes up so much space without much give. The ride is somewhat softer than a normal inner tube but if you are in a place with a lot glass in the streets or other tire puncturing devices then this is a suitable option.
