I've already replaced one tube with an alternative. Instead of foam insulation, I'm trying rubber. I sat on it (240 pounds) and my wife couldn't figure out which one was the air tube and which was the rubber insulation. I'm going to play a round with one in each and see if there are any observable differences. One early observation (and I hope this doesn't last) is the rubber insulation seems to be squeaking as it rubs agains the rubber tire. Also, since the rubber doesn't inflate, the tire is not seated on the rim yet. I'm sure this will subside with revolutions or maybe even a quick blast through the stem hole with an air compressor.
Can you tell which is which?
