Wow!!! that brings back memories. Split rings, non-split rings, and non-split rings with a split lock ring. All of these could kill. When I was 16 I was the tire guy at a local garage. Every night there would be 5-10 flats from all the tree trimming contractors trucks we serviced. We did have a proper cage though with a way to monitor, and pressurize/ depressurize from a safe distance. Not like the expanded metal POS in the video. You will drop a load the first time you see one let go. I cringe everytime I see a video of idiots reseating beads with starter fluid. It can burn the inside of the tire and weaken it causing a similar situation with even tubeless tires. Several Bubbas have died doing that.
