you cant seriously compare an oe wheel thats had years of development and rigorous safety testing to a wheel thats been chopped and widened by someone in a workshop? how much testing do the banded wheels go through before a tyre is stuck on it and its on the road?

there will be some banded steels that will be done to a high standard, but personally i wouldn't risk it. all it takes is one hairline crack in the weld or one bit of hard brittle metal, you clip a pothole or bump and it cracks or splits.
