Yes, incorrectly fitted tyres are lethal, but a good tyre, which is designed to be inflated to 115psi being used at 90psi or 80% of design pressure is incredibly unlikely to fail.

The worst are the type with the steel ring like what used to be on the tankers when they were fitting the Russian tyres, lethal things, think the local tyre shop won't work with them anymore.

It is the total energy stored in the tyre that is a thing to worry about, which is a function of the pressure and tyre volume. A large tractor tyre bursting at at 15 psi would be a big boom.My Ifor 12" wheel is meant to be 95psi
I would not want to be right next to an Ifor tyre going pop, but it would be a fraction of the bang a super single at the same pressure would have.

As you say @clbarclay , volume is the killer.
I run our Ifor tyres at the recommended pressure, it does them more harm than good running at lower pressure imo, despite it feeling like lower pressure may be kinder to the tyres.
I’ve had terra tyres explode, at 20-25 psi, I’d not have wanted to be next to them at the time! That volume of air escaping at once has incredible energy.
Likewise, dumptruck tyres, on big articulated trucks, will be running circa 50psi, but with a huge volume, and have been know to damage adjacent machines when they go pop, just from the air movement.
I think most of the accidents that happen during tyre inflation, are due to some sort of fitting error or defect in the tyre or rim.
Split rims are potentially dangerous, but there are many thousands of split rims operating on earthmovers all over the world, once they are fitted properly then they are safe as any other rim.

I find running our tyres at about 75psi much better, I run a tri axle graham Edwards on the 10” rims. They don’t seem to rupture the steel belt and pleb with less pressure. Stone tracks and potholes in roads are very hard on them when loaded. I have actually been able to wear the tread out on several now!

Split rims are great to work with if you’re careful. Did one only yesterday, usually put the airline on them in the telehandler bucket and duck behind the back of the bucket when pumping up to full pressure.

From the Dunlop Agricultural Tyres book by Frank Inns & John Kilgour
I saw that photo years ago as part of a lesson, also mentioned the importance of a cage but the tyres I changed were too big for cages. I used to blow them up with wheel fitted to the truck parked against a wall and no valve in the tyre (no inflator just airline straight to tyre), that way if it was going pear shaped you could pull the airline off from a safe distance and tyre would dump pressure. If it went well you could pop a valve in and top up.

Airlines should have a pipe of a minimum of 3m long between the trigger and the valve coupling, in my opinion.
If you don't stand 3m away that's up to you.

Not strictly Ag related, the new dog/baby gate latch clearly came from a newer model, so the old pin was too small a diameter to latch in place
A grinder and M10 coach bolt came to the rescue:

Loader tractor clutch cable failure on a Saturday afternoon - fortunately no damage done. Clevis snapped in the process too.
Found a surplus barrel nut left over from building a kitchen, and welded up the clevis. It’s a temporary repair, but got me home.
