Dangers of welding wheels.

[honestherman]

Got a question Guys. I have a GMC 7000 with Dayton Split wheels 20" on it.
I will never use it to capacity weight. So I was thinking Getting a tubeless wheel that I can use or have made to use a LT tire on it. Not a split rim.
Any Ideas guys? I see the new Dodge trucks have a 20" on them. So I just want to get rid of the split rims 900 20's
Do you know anyone who makes a wheel that I can use?
Thanks Guys

Are you sure they are Dayton wheels?I'm more inclined to believe that whats on that Jimmy are 20'' hub-piloted wheels with a solid lock ring and drop center wheels(unless this is an old,old Jimmy in which case what you have are "widow-makers"These are the wheels that had no lock ring-they split in two).Dayton wheels use a cast iron spoke hub and the rims are secured with wedges and log nuts, either a 5 or 6 spoke hub.Your truck should have a 10 hole budd style wheel ,with one set of ten lug nuts holding on the duals and 5 studs/nuts on the steer axle.If this is indeed what you have, then the next question is what year is the truck?If it's 70's or newer it should have the solid lock ring variety.

Regardless of which wheel you have, your only option for what you're looking for is custom made.Big $$.

i think after discussions in another part of the forum regarding welding wheel rims it's about time this thread was brought back to the top for those members who haven't seen it before. I'll also include the link I posted on the other thread out of interest. The guy who wrote this article and myself were part of a team investigating a fatal accident where a LF tyre on a large haul truck exploded and killed the operator. The incident is mentioned on Page 4 as is the root cause of the explosion (#6 on the "initiators" list on Page 1). IMHO what he doesn't know about OTR tyres isn't worth knowing.

Thanks also to Jonas302 for digging up the thread and posting a link to it in the other discussion.

Thanks for posting that report Nige Some really good info in there.

Got me to thinking though about the TPMS systems... I wonder if it would be feasible to have the sensors sense for oxygen >5% ? since this would be one of the main factors in providing the necessary ingredients for explosions...

 

[Nige]

You'll note that for an explosion caused by diffusion there is no requirement for any oxygen at all to support combustion.
This is scary sh1t TBH ............

If they are truly Dayton 20", then 22.5 non-split rims will directly replace them.
Been slowly weaning the 10.00-20 rubber off my '69 Brockway.

We have a local tire company come to the shop and dismount/mount tires for us. This last summer they were up changing some tires out and one of the guys
was inflating a steer tire that was just mounted on a 22.5 aluminum rim, He was just getting ready to install the core and the sidewall zippered. Filled his pants
he did trying to get away from it. No one got hurt, but when one zippers you will know the sound it sounds just like a zipper as the side wall gives way.
Top name brand tire too.

The zippers will make all of yer hair stand on end! I have had 4 different ones zipper on me over the years.

this needs to come to the top again. maybe save a life.

I have just shown this to our fitters, seems they have been heating stuck wheel nuts for years!!!! they won't be now though.

I'm going to bring this back to the top again, for no other reason than I came across the report written at the time by the tyre expert on the investigating committee. Photos are on Page 10 onwards.

What was the wood used for in shipping the tires anyway?

What was the wood used for in shipping the tires anyway?

It was common to use short-ish lengths of 3" x 3" timber as a separator between the beads to keep them apart, basically to keep the tyre in shape if they were laid flat and double/triple stacked. Either that or it was cribbing placed under the tyre so that it could be handled by a forklift. Either way whoever mounted those tyres was not taking care to make sure all foreign material had been removed from inside them before installing them on the rims and inflating them.

I worked for the Port of Seattle at SeaTac airport for a short time. One of the other operators was injured but very lucky when he and a co-worker decided to work on the jetway tires and rims, separating them for recycling the metal.

These tires and rims were laying about and they thought it was a good idea to deal with them in a slack time, but neither of them had any tire training or experience. Just a glance will tell you they are highly loaded multi ply tires with more than 100 PSI in them, that they neglected to deflate first.
They started taking the split bolts out till they got to critical load and the remaining bolts partially sheared. He got slapped pretty hard but both could have easily been killed, just like in this video that TS posted.
It was one of those " IF I had only known what they were up to" moments, as I do have that experience.

I went on an EMS call, guy got a new trailer, his brother in law had a car with 14" tires, they decided to mount the 14.5" trailer tires on the car rims. It killed one of them, and the other was blinded and lost both hands. I always figured the dead one was the lucky one.

I hate tires. Last time I aired up the tires on the wheel loader I clipped on the chuck and walked 50 feet back to the shop and turned the air hose on from there.

Seen a 797 tire blow from a quarter mile away and that was scary enough for me.

 

[Randy88]

Jet tires are not air filled, think its nitrogen they fill them with, watched it done before, but that decades ago now, if regular tires are not bad enough, jet tires are far worse in my opinion and far fewer are even qualified to work on those compared to regular air filled tires.

The joke at the local airport years ago was, if you can afford your own personal jet, you can probably afford to pay someone to come a few hundred miles one way to change a flat tire.

What's amazing is how many tires are installed on aluminum truck wheels that have worn out bead/seating
on the rims. After ten years and X amount of miles the rims are pretty tired in most cases.
