[Jon Stratis]

We for a cheap, low weight solution, we took a bike tire (the inner tire tube, not the wheel) and slide it onto a section of PVC pipe. It was a little tricky to do - we had to close one end of the PVC, get the tire started over the other end, then inflate the tire with enough pressure that it could slide on easily, but not so much that it burst. Once the air pressure is gone, the tire fits very snugly.
