Tire blowing off rim while being aired up.

A friend of mine had a fellow killed by a split rim a few years ago.

Fwiw you should also look for videos of welding on rims that have tires mounted on them, valve stems removed and beads broken don't always help. Even on standard rims they will blow up on you as pressure skyrockets.

I didn't think split rims were used anymore. Shows how out of touch I am.

Earthmover tires on 25" rims are still split rims, however the 3 piece shown in the video should be used for up to 20.5R25 tires, 650/65R25, 23.5R25 and bigger (also this 29.5R25 shown in the video) should be used on 5 piece rims with higher beads. I guess they put it on a 3 piece rim with low beads just for the video because new tires and rims dont just blow like that... However at work they allways seat the beads with the tire still on the bead press bench, so the overhanging structure will catch the locking ring and wedge if they are mounted improperly.

80% of all these accidents with multipiece rims are caused by improperly mounted locking rings, another 19% by bad old tires, and 1% are freak accidents with new tires, i estimate.

WOW.Lucky he was just leaning backwards before it blew.

Also good he had one foot on the tire, it backflipped him away.

I dont know if it actually saved him a broken nose or jaw, the landing looked pretty rough

Years ago some friends and I took a trip with our dirt bikes. We took two vehicles both with trailers. When we got to where we were going to ride we unloaded and then started to get our riding gear on. All of a sudden one of the little 5.70- wheel just blew up. Being a gravel parking lot it threw rocks everywhere and peppered the car parked next to it pretty good. For how small that tire was you wouldn't think that it could be dangerous. Had someone been walking next to it when it blew I'm sure it would have drawn blood or worse. Whenever mounting tires I always dread beading them simply because of how much energy is stored.

In the military, they use a stand off inflation gage with a 10 ft. hose. I saw one go and the operator was lucky
he was at the end of the 10 ft.

That guy is lucky indeed.
Knowing the dangers of split rims.
I have 3 piece rims on my wheel loader.
After fixing a flat or when mounting a new tire I pump them up to 10 PSI,checking the seating closely, if it looks OK i bolt the wheel to the axle and bring the tire up to pressure
