...on US military vehicles.
Here's a description of what they can do:
I remember picking up the pieces of a young trooper in Vietnam while I
was serving there in '69 who had the misfortune to be sitting on top a 2
1/2 ton wheel when the split rim decided to depart company with the
remainder of the wheel. The force of the explosion threw the guy almost
30 feet into the air and broke his back! Split rims need to be
respected!

probably worth bringing up. I don't have a great deal of experience in this
field but can tell you two stroies that were to passed on to me while I was
in the Marine Corps by instructors hoping to instill their students with a
proper respect for split rim wheels. First of all don't hold on to the cage
bars while you fill the tires with air. One kid lost all four fingers of one
hand from this simple mistake. Another fellow was standing on a split rim
when it blew. It shot him THROUGH the corrugated steel roof of the tire shack
18ft above the ground. Needless to say the various forces that he was
subjected to in this explosion, impact, and fall, killed him. Big Time. I am
not so worried about the bolt together split rims used on WW II jeeps it's
the snap ring truck tires that are the killers and there really are no
warning signs that can be counted on to tell you which ones will hold and
which ones will fail.

And finally, from the land of Ford Trucks, somebody asks an important question:
This thread is just my annual split rim safety rant. I hate em. It angers me that the US can afford the finest military aircraft, but only half of the ground equipment has safe (bolt-together rims). I know many of you stockers are faced with this danger. And it doesn't end after install. Even re-inflating a split rim that has gone low on air can be dangerous if the ring slips a bit. Get a clip-on air chuck so you can inflate from ten feet away. Preferably on the other side of your truck. Make sure the nieghbor kids and the Mitsubishi Eclipse aren't in the line of fire.

I bet those new Stryker vehicles (with their 6 wheels) have split rims, too.
