I saw a tube like that once. I asked for a 110/90x19 tube and the parts guy brought out what looked like a shoe box with reinforcing tape all over it. When I took the tube out to look at it, it immediately took the shape of a tire, and looked as if it could have been rolled onto the rim and run by itself, perhaps without even inflating it. I asked him for a lighter tube. He had trouble getting the HD tube back in the shoe box, so he set it aside until he could get a couple guys to help him, and brought out another box. This one looked like it was originally made to package a radiator cap. I went to another store.
One flaw it this system is that unless a tire is made as a tubeless tire to begin with, the bead may not seal very well. In fact, absent a layer of rubber on the inside specifically designed to seal in air, the tire itself may leak. That, and I fail to see how it's any more flat resistant without a tube than with one.
I run Moose Hd tubes or I will get 3 flats a day running 14-16 pounds. Lots of rocks here. You think a shoe box is big, outta see the box the moose comes in. This idea is great not as good as Chad Reeds set up, but great. I have 2 buddies running these with zero problems at 10-12 pounds. If you are riding on tracks with zero rocks etc, might not make a difference but come here and your mind will change, or you will be changing tubes all day. They Work Period
