When I started in the truck maintenance business, over 1/2 our fleet still had split rims. First thing I was taught about split rims is to let the air out first thing.
Then the last thing we did was put the air back in after the wheel/tire was mounted on the truck with a long hose and clip chuck.
We did not have a cage, never did get one. Glad those things(split rims) are mostly gone now except for on industrial equipment.
The dude in the vid had no idea what hit him!
Same here I started as a young lad in the 70's working on cement trucks. flat beds, tractor trailer, doing split rims and brake service, we had no cages either, all it took was the first time a ring came off inflating a tire to scare the living $h1t out of you! to handle those things like live grenades...I still see a few old dumps nowadays still running splits, no way Jose! that I'd touch one today
