Trailer Tire Inflation System...Ever seen them air up a tire broken loose from wheel?

As the title says, have you ever seen a trailer tire inflation system air up a tire, that was broken loose from the rim, while the trailer was in transit? I'm asking this from a discussion on another forum.

Back several years ago when the company I worked for at the time first started getting trailers with tire inflation systems a friend told me that he had a tire broken loose from the rim that was seated and aired up when he got to destination. I knew the guy wouldn't lie to me but I still thought to myself, I don't know if I believe that or not! Later on I had the same experience. Since then I've had it happen approx 4-5 more times.

I guess somehow when in motion the tire spreads and seats enough to take air. Not exactly sure how it happens.

Just wondering if anyone else here has had the same experience.

 

I was really surprised the first time I personally saw that it did seat and inflate the tire. Just hard to imagine how it spreads the tire enough to seal enough to take air.

I've wondered several times, with the fact that this happens, why the tire was broken loose from the wheel to start with.
