No idea exactly. There is a process whereby these are heated to get them back in shape. The wheels were sent to Shershah for fixing. Thankfully, it was the insides that were problematic so whatever they did for fixing, it didn't affect the outer finish.
They weren't exactly bent, and it was something that was not visible to the naked eye. But when placed on a machine, it could clearly be seen that they were way out of round. All wheels are out of round (even new ones) and they are kept that way intentionally, but these were way too much.
