I'm getting this feeling that most here are not young pups.....
.
I looked up the NoMar tire machine :
https://www.google.com/search?client=firefox-b-1-d&q=no+mar+tire+changer YIKES ! $500.00 ! .
If I had a shop I'd budget for one straightaway .
In..... (197?) I got a job at San Gabriel Motocycle Salvage, Fred Merkel was the propritior and me being the new guy of course gut stuck doing tires & tubes . luckily at that time few alloy (Akront etc.) rims were in service so I got a 35 gallon grease barrel and laid a bit of short nap carpet over the open end and used that to support Motocycle wheels as I buzzed them off and on by hand using long tire irons .
If you do it daily it becomes *much* easier ~ today's tire beads (the part against the rim) are much,
*MUCH* stronger than the old days .
I don't trust tubeless tires on Motocycles, I know they're safe and all that .
If you really want to reseat the bead on any tubeless tire in the bush, go look on you tube under dune buggy tire seating but don't say I told you to do this when you're in the hospital .
This is just one more of those things that are *very* dangerous and so shouldn't be done but you mentioned it .
Along with pulling the tube out the side of the tire, we also often had stem leaks and so would need to modify a patch with a hole so it'd slide down the valve stem and seal a stem base leak...
There's lots of things I know how to do that I don't recommend .
I call them "Farm Fixes" but I learned many in 3rd world places too .
