We have a nice winter weather now, but I cannot afford shooting a video on a workday. On the other hand, our weekend weather is forecast to be warmish. On the next opportunity, when stars align, I will try to put a wheel + my regular equipment out to freeze and shoot a video of a studded tire being taken off and put back on in the field. Heck, I'll try to do both 700c and 16". A studded tire is just a tire. To underscore the role played by the state of mind, when I was first putting a studded 16" on, I went into a complete panic - the smaller tires leave you well less margin to maneuver than large. I damaged the tube twice in two consecutive attempts. After I did it few more times, with more thought put in, it is now no different than large, basically deserving a yawn.
Look, I don't know what you are trying to prove, but you are missing the point. If you really want to address the concerns similar to the considerations of the OP (me), then I suggest you do the following: Ride for 2 hours at -5 °F. Then, out on some random trail or road, make a video of you easily changing your tire. With your superior state of mind, I'm sure that too will be a yawn.
There has been some very helpful advice and discussion on this thread. Thanks all.
