For those folks who are interested:
First, that video is of a type of tire used on lawn and garden tractors. They didn't identify the size, the max pressure, nor the load rating - and that's important.
Engineering practice says that if you are designing something that is going to be subject to cyclical loading (which pretty much describes what a rolling tire is are all about), you need to design it 4 to 5 times stronger than a one time loading does (and a burst is a one time loading)
So 166 psi divided by 4 or 5 yields 42 to 33 psi - and probably right in the operating range, if we knew what the tire was.
Old tire? Age affects the rubber, much much more than cords (which is where the strength comes from) and I'm guessing this is nylon, which is pretty age resistant.
Truck tires, which are inflated as high as 150 psi, would react differently.
So be careful drawing conclusions from videos of this sort. There are lessons to be learned from them, but the details are important.
