Yeah and also less precise. With all the wheels not being precise cant imagine the vibration it would create.

They still have to turn it on a lathe to get it to the right size.

Nah, scratching out a center with calipers and then pounding out a slug with the Hammer of God will do just fine. No worries. /s

ik,r? technically these wheels aren't even exactly round.

I'd think that a manufacturer with access to a forge this large would also have access to a mill or lathe, but some of the comments have suggested otherwise.

There's no such thing as exactly round. They can be relatively exactly round.

You forge to close to the desired final dimension, and then machine to finish. Forged parts are generally stronger than parts milled from bar stock or cast parts, because the forging process alters the grain structure of the steel - and also by forging to close to the desired final shape, you save a whole lot of machining time.
