For some reason, I can't seem to get the tire back on my rim. I put the tire in my suitcase when I was flying home, and I now have been sitting here for a couple of hours, but I can't force the tire on.
First, I partially inflated the tube, then placed the tube in the tire, then tried to get the tire back on the rim. I can't get about 25% of the tire on the rim.
I wondered if perhaps the metal on the rim expanded. I just talked to my friend, who is an engineer, and he said that even if the rim expanded, the rubber would too, since they're both at the same temperature.
Am I doing something wrong?
