Super. Yeah, that's definitely comforting. The same fix-a-flat stuff would also be a workable solution in a tubed tire. I had a tube issue a couple years back and I really wish I'd have just done that. I cost myself a lot of time by not doing it, and having a tube and tire driven to me. Some areas in the U.S. are just too far from parts. In that particular place, I was about an 8 hour drive from home, with not any major cities for at least 4-5 hours from the area. So I really am now gun-shy of being stuck somewhere. I now always fly with a spare tube for each size of tire on the plane(s). With a tubeless tire system, I'd have to consider though, do I want to carry a spare tire, or can of fix-a-flat. The latter is lighter, but, if the tire is really the issue, I would have been out of luck up in that stuck situation. However, even a tire with a decent sized hole can have a tube stuck it in and still do a job.
Tires and me have never been good friends, I guess. If I had a dollar for every boat or camper trailer tire that ever blew out on me, I'd, well, be able to probably buy a new tire.
