Yikes. My local tire shop owner just ripped his finger off on a 10.00-20 lock ring that was in the tire cage. Been a tire man all of his life. reached in to check the pressure and the ring blew off. :(

yikes indeed. When I was a high school lad, I worked at a gs station/tire shop evenings and weekends. We did not have a cage so I would hide behind the Coats 20/20 that was bolted to the floor and use the air hose and pedal to inflate the 16" split rims on the 60's Fords.

We had one lowboy with split rims by the time I was in jr high the only way we ever worked on a tire was with a backhoe holding it down and a 5 foot air hose on the chuck

Knock on wood I never blew up a tire, but have witnessed it happen. I'm accustom to thinking it's only old dry rotted worn out tires that are suspect to exploding. Tires with damaged side walls are also suspect. New tires!? Never thought about a new one giving away. Was it a chen zen special or were they just mishandled?

I was working at a small coal mine and had an office in a trailer that sat across a ditch from where the haul trucks were parked at night. The mine was running two shifts so the trucks would be parked when I came in each morning. I came in one morning and saw one of the trucks parked straight across from my office but didn't think much of it until I opened the door and saw everything on the ditch side of the office scattered all across the floor and lots of distortion in the wall paneling. I went outside and checked the ditch side of the trailer and saw the damage. I called my night mechanic to find out what he knew. The trucks were 773B with 21.00R35 tires and this particular truck came down to the shop late in the shift . The mechanic saw the bulge and had the truck parked and kept everyone away. He said it took about five minutes and it sounded like one of those blast boosters we used for blasting in the mine. I gave my guy lots of praise for recognizing the danger and making sure everyone was kept away from the truck. The mine mangers weren't so cavalier about using old recapped tires after that.

Haul truck tyres letting go reminds me of this event from a few years ago, but in this case it was a lightning strike that did it. The tyres didn't pop off until 4 minutes after the strike which is kinda scary.

Somewhere in the archives here, is a thread about welding on rims. It's been proven that heat somehow causes a run-away chemical reaction inside the tire that ends with an explosion. I'm sure that's what happened in the lightning strike.
