The poor boy ... rest in peace. I've had a couple close calls with O/A bottles falling from several stories up or slipping on morning dew on some steelwork. Just lucked out, I guess, until I got wary.

I saw a 10.00 20 let go(ring was not seated right) when I was 19 at the truck tire shop. The guy filling it had the inflator on a long hose and was out of the way, the ring mark is still on the concrete wall to this day.

One of my best friend's father ran a service station back in the 60's and 70's in Hermleigh, Texas. Who can tell me where that is? I'll bet that Dubby can. Anyway, that was when they did flats, changed oil, etc. He was airing up a tire on a rim that had been run flat. I'm not sure whether or not he was aware of that, but the tire blew off of the rim and hit him in the head. He was never able to work after that and it really messed him up mentally. This wasn't even a spit rim. According to my friend, the rim hit the ceiling of the station hard enough to leave a dent in a pipe up above.

Always be more than careful when airing up tires.

Yea cause it isn't just split rims that can get you. Zipper sidewall separations can be deadly too.

One of my former jobs was to fix truck/tractor tires. We didn't have a cage, but did have a "safety" that was basically a piece of channel with a center solid piece that held another piece of channel over the top of the tire. It wasn't bolted to the floor, but allowed to move.

Our air supply was regulated to 35psi, just enough to seat the bead & we could seat the ring with the bead breaking hammer. Light taps all the way around with about 15psi in it, then inflate it to 35psi if it was still together, we let it sit for a while.

Once it was mounted on the truck run a chain through it to the frame, put a clip on chuck, add high pressure air until inflated to appropriate pressure.

Never had one come apart on the truck, the boss did launch the "safety" & tire up 25 feet to the ceiling & dented a roof purlin.

I did blow the sidewall out of a tubeless 18.4x36 tractor tire. I had about 12psi in it & was almost done with the fluid fill. I had to change my shorts when that blew.

Sorry to hear about the youngster. Working with machinery, tools, air filled containers can be deadly if not respected. Let's hope the community remembers this for a long time & another youngster doesn't do the same thing.

For this reason alone I hydro-stat any tank that I plan on using for air. I will pressure the tank up to 150% of its rated pressure and if the working pressure is not marked I go 150% of the pressure that I plan to put in the tank.

Sorry to hear about the kid. Too young for something like this to happen. Heck, you are never old enough for something like this to happen.

My close call came not from a tire, but a snowmobile primary clutch. We were in a buddies garage working on a sled, and one guy says "the clutch isnt running true", and put his hand on it. I leaned over to eyeball it, and it seemed ok, and the guy with his hand on it (just running uner his hand so he could feel any "high spots") says "I think its good". Just as he pulled his hand away, the clutch exploded into a hundred pieces and shot shrapnel all over the garage roof. The big pieces actually moved my hair as they blew by my head! We all signed the holes in the ceiling, and the owner of the garage swore he would never repair it as a reminder.

WOW I don't like hearing that. Those tires and rims have my full attention when doing this. When I was 20 I worked in a truck garage and I had to change snap ring wheels for trucks. They were the 2 and 3 piece rims. I pounded truck wheels everyday until there was another new guy hired to do it. I always sweat bullets doing it. I was a tough guy in them days. They told us that snap ring could fly right off there and I believed them. I only have used the cage when I was in school. All my employers never had cages. I hate doing them rims. The most recent snap ring wheel I done was about 6 monthes ago and it was on the manure spreader. I done it very carefully, I didn't have no cage either. I did sweat bullets.

The salvage yard where I worked had no cage, but they put their loader forks across the tires when seating them. I stayed far away.

Aircraft tires will kill ya too. An Army unit didn't have (they are under 200 bucks for fucks sake, I've ordered them for USAF toolrooms) tire servicing kits (nitrogen valve/guage/blowoff safety valve) and were "hot shotting" helicopter tires straight off the nitrogen cart.

The "detailed" part of the unclassified safety report made military circles (I read it while on active duty) but didn't go very public. Methinks some supervisors would be toast but those details were of course omitted.

It's now hard to find the entry admitting WHY the tire blew.
Cages are nice, but they aren't always available. Don't hotshot and never stand in the blast radius when airing up (any) tire:

On October 21, 2003, a Black Hawk tire exploded during inflation at the air base in Balad, Iraq. The cause of the tire explosion was
gross over-inflation when technicians connected to a high pressure nitrogen source without a regulator, rather than a low pressure
source as they thought. The result of the explosion was significant damage to the area of the helicopter around the wheel assem-
bly. More importantly, one man lost his life, and another lost two limbs.
Not that many active G.I.s read this, but if you have ONE broken tire kit you can split it and turn them in (they are XB3 and are condemned, check your code) as TWO separate kits so you can order the extras you WILL need since they get the shit beaten out of them. The authorized quantity is always stupidly low and good luck getting them at deployed locations. On the military sin scale, some creative supply abuse is better than losing sorties or creating combat necessity where folks get hurt. Storing the spares in the "awaiting calibration" bin etc works well.

Yep, worked in a tire shop when I was 16, the guy that ran the place always had us wire brush the heck out of the rim and locking ring till they shined.

Always well lubricated also and always in the cage. Never once had a problem, and learned a lot from that guy also.
