However, I do have one concern. If you can stretch an airless tire into a rim, what's stopping it from coming off (you can't take off a conventional tire once it's inflated). Obviously, these things have been tested extensively otherwise they wouldn't be released into the market by now... so I have to assume it's not an issue.

I hate flats, so I'll be keeping an eye out for user feedback on this thread...
