We Break the Huge Cruise Ship into Pieces And made Truck Rim Plate For semi trucks 

Those are not too bad, though you must use caution. Though I once dropped one on my toe,, which aches all the time now!! I sell tyres but like most places refuse to do them now. The only reason they need them is the trucks are grossly overloaded at all times. And shitty old steel to make a ship is not the material to use.

да!про диски было уже но это вроде другая фабрика

It doesn't help here that the metallurgy of the steel they're using as base material isn't exactly documented and simultaneously was exposed to salt water for quite a long time before it was turned into wheels. Steel this easily bent (ie, not subject to some kind of heat treat in the process to form it) isn't especially strong to start with. Unfortunately a lot of what we see in these videos is like this, the provenance of the metal is unknown. The workers are clearly trying to do the best with what their employers have provided for them to work with, but between the substandard materials, the worn machines, and some pretty significant lack of calibration steps means that the material isn't even loaded straight into the lathes to begin with.

Cracked rims are actually pretty common in the United States, my friend owns a truck tire service and he is always getting called out to dot inspection points and scales when trucks are put out of service.

@@ChrisHarding-lk3jj in Europe we dont have old enough crap still on the road for rim cracks to occur. Perhaps in Africa or Suriname where our old trucks go, they have issues with cracked rims.

Sure, tires on split-rim wheels can be field-changed without as much in the way of special equipment in theory. But they require tubes. Single-piece wheels don't usually require tubes. Since modern safety practices want to see these sorts of wheels dealt with using special equipment like cages at tire shops, it's less useful to have something that's theoretically field-changeable if that practice has ended, and requiring tubes means extra parts. If they all have to go to the tire shop then it probably costs more to have these worked with than to use single piece wheels. The three-piece dayton style are the ones I find interesting, but still dangerous. By separating the hub from the rim assembly the spare takes less weight, but the risks for dealing with the lock ring still apply.

@@TWX1138 i mean yeah, but tubes are light, and easy to repair but really its, about forcing folks to buy "modern" equipment, i.e. specialized labor intensive to service

@@northmanlogging2769 its very rare to see a trucker change his own spare wheel here in Europe. Mostly they just call the tire shop mobile service, with a big impact wrench and a decent jack. International drivers change a spare because they dont know if local tire shops are trustworthy.

@@Sjanzoits fairly rare in the state too, unless you're a broke logger that can't afford the roadside service call... or if you get a deal on tires and the tire shops refuse to install them for one lame excuse or another.

Nope, modern as well as classic rims are rolled and welded. Heavy three or five piece earthmover rims have cast or forged parts welded to a standard tube.

I think this would have been the case in many developed countries by 1990
