Clare, Xeno.... did you ever have a batch of tires that just wouldn't seal after the final bead?

"Authorities did not provide any additional information about the incident which is being investigated by a number of agencies including Cal/OSHA and the Los Angeles Port Police." Since it occurred on MAY 15, 2019, we might be able to find something about HOW it happened (e.g., were they using the flame method?). This is one thing that's a problem with news, which is that they don't bother to close the gap when they find out more, sometimes. I searched for more information that was recent but haven't found it yet, so we really don't know what happened. It does seem like those BIG tires do kill workers though... February 20, 2019 Worker Killed By Exploding Tire At John Wayne Airport <https://losangeles.cbslocal.com/2019/02/20/worker-killed-by-exploding-tire-at-john-wayne-airport/> "One worker was on top of the tire, and the other on the bottom, when it exploded." In both cases, I'd expect a report somewhere from Cal OSHA. Here is a list of their main risks: <https://www.vehicleservicepros.com/shop-operations/training-resources/article/10628402/osha-releases-new-tire-training-resources> |

Plenty of stories about exploding tires on split rims from improper technique which have nothing to do with fire. This is why large truck tires on split rims are inflated in safety cages. https://www.hsa.ie/eng/Safety_Alerts...it_Rim_Wheels/ |

Apparently, from the safety alert at the bottom of your reference, these "split rim" mountings are used mainly for LARGE commercial tires, is that right? <https://www.hsa.ie/eng/Safety_Alerts/2015/Large_Tyre_Inflation_Alert/> If so, I wonder what's different about large commercial tires? o Obviously size is one thing - which could mean more energy o The pressure per unit area "might" also be different o Maybe mounting needs determined the reason for the split ring? I don't know yet ... so I simply ask ... WHY ... they bother with split rims for these huge commercial tires? Is it mounting considerations? Or some other reason that they use split rims for such huge tires? |

Tyres have the potential to *create their own* flammable gas inside the tyre. It is why those truck tyres explode and why an inert gas (nitrogen) is used to fill them. > Plenty of stories about exploding tires on > split rims from improper technique which have nothing to do with fire.

WHY ... they bother with split > rims for these huge commercial tires? They are *huge*, to large and inflexible to work by hand. They also have a *flat base rim* and not the well base rim you would be familiar with. Think how well you would fare changing a tyre without that well in the rim. > > Is it mounting considerations? > Or some other reason that they use split rims for such huge tires? > Yes and more. -- Xeno Nothing astonishes Noddy so much as common sense and plain dealing.

It is why those truck tyres explode and why an inert gas > (nitrogen) is used to fill them. so this part is not true, truck tires usually blow from underinflation so they get hot and fail,(read tire has a leak) or the carcus has a mechanical failure. they run hot and under high load so failure is not to be considered abnormal, but low considering the amount of total miles run by trucks, and also retreads from the not so quality retreaders using poor carcuses is a factor.

BTW, while a half dozen tools & techniques were proposed, it seems the best is the "bazooka", where here's one guy showing how he crafted one from a spare "truck" air tank. <https://youtu.be/PkqNIG5IZm4?t=522> |
