Leave the wheel on the machine and call out the tyre people that you were going to take the wheel to,no use taking it anywhere cept people that do that type tyre,if they are handling large tyres they will not remove the wheel to take the tyre off should they need to, they will have on board their service truck what we call in the UK a tyre seating bead blaster, a portable tank that connected direct to the filler and when the trigger is pulled it blasts the contents which could be a hundred Lts or more of air (depending on the size used) out in a millisecond and that will push the tyre back in place,it will then have the filler valve put back and be pumped up. I have managed to reseat large tyres by taking the weight off and using a rachet strap around the middle of the tyre and tightening it as tight as possible and walloping it with a 14 pounder using plenty liquid soap (washing up liquid) to get it to seat,the very last option would be taking the wheel off.
Good Luck

Was reading along, just a reminder, if that is a wheel type that has the locking ring that can fly off, stay out of it's trajectory when fooling with that tire. We just lost a young man, who did 2 tours in Iraq in the Marines, wife and 3 kids behind. While on a snow removal detail, apparently he was filling the tire, not really sure what the details were, just beware if that wheel has a locking ring on it.

Yes Billy very valid point that,loads of people are killed by tyres throughout the world every year,the tyre people will have the proper safety cage and they know the dangers.

I was working in a pit years ago and they had this huge loader with 33.5 tires. One tire guy was killed and another seriously hurt when a rim blew off. It was a gorey scene and they had to sell the machine after that. We had a tire guy once who refused to inflate our DW21 tire after a repair. Had to blow it up ourselves, as always there is lots of pressure to get going. Phil

I agree, you really need to be trained to know how to work on these, what to look for that will cause a catastrophic failure, and what steps cannot be risked, prior to inflation. It's obvious that the wheel/tire assembly components must not be damaged, rusted, cracked etc., and they must be assembled so that when the tire is pressurized they lock in as designed, I can only assume bad things happen when the components are askew, misaligned, damaged and or cracked. Staying out of the trajectory of the wheel assembly is not always possible, you can inflate it in a cage, but you still have to mount the darned thing, hoping that it's locked in place.

I'm familiar with the 920's, 930's having operated same, as well as 966's, 980's, and the komatsu WA-450, + a few others, yet in the years I spent time in the seat earning a living operating equipment, I was fortunate to never have had to deal with any wheels or tires on these, including the 627 scrapers and TS-14's 24's. I can see where a person may think nothing of hooking an air chock to the valve stem and adding pressure, or trying to inflate a tire that should be otherwise worked on by a properly trained tire mechanic.

Reason I say that is no one ever trained us about these, had heard of tire explosions in shops, but no details, just heresay. I 've seen first hand what can happen when a 110 psi steering axle tire lets loose with 29 ton in the dumpbody while going 45 mph, they never found the ring as it went into the woods, front fender blown to pieces, and the battery box cover blown off, was an R model Mack tandem dump.


No one from any of the companies I worked for ever educated us about these tires, instinctively we always called the foreman who called the shop that would dispatch a tire mechanic or their own mechanic. Many of us would gladly help or do something when possible to minimize a service call from our in house mechanics, at least lessen the urgency or get a truck back to the shop, like I have done many times when a brake can diaphragm blew while on the road, I'd bypass it and head to the shop in good faith to be helpful and make it easier to repair than on the side of the road.

Point is, this fellow may have been doing the same thing to be helpful, not sure if he did any electrical/mechanical training as his m.o.s. in the marines, or had any civilian training on these wheel assemblies, but I'll bet he was trying to get the loader up and running thinking nothing of the danger when inflating that tire. We've had 4 veterans( think the above article mentions this) in our area that have been killed after surviving combat tours in freak accidents, and during the vietnam era while my father was on a massive state project as a concrete superintendent (who was also a veteran) with a 40 story high rise where a combat veteran had just returned, was killed after a fall, hoist operator moved the elevator car without him knowing, he fell 19 stories.

Well, after reading all the good advice, I removed the tire and took it to town and had it fixed. We broke the lugs loose by slowly lifting a long cheater pipe with a small JD 770 tractor loader. When the cheater pipe was under tension I gave it a whack with a sledge on the low side. When the nuts gave the loader would jump up about two inches. We stayed well out of the way and took everything very slowly as we worked. After we got the nuts off, we had to use a port-a-power to push the tire off the wheel. As the tire wasn't filled with salt water, we could handle it with the little loader.

I definatly do not want anything to do with lock rings and airing up tires while standing in front of the lock ring. I use a clamp on air hose and stand back to air them up. Out here in the middle of nowhere it isn't that easy to get tire people out to service equipment miles off of paved roads. It's also expensive because the tire people would rather service the coal mines and construction equipment around town than waste a lot of time getting to a ranch for a small job.

The local CAT dealer had an employee killed a few years ago taking wheels off one of the larger CAT loaders so it could be hauled by truck. The 8000 pound tire fell on one man. His partner actually walked on top of the tire that was laying on the unfortunate man before realizing that the other man was underneath.

Thanks to all for the good advice and safety reminders.
