Problem with reproduction steel wheels

1) something is not right- measure the angles of the lug nuts vs the rim lug holes.
2) how does the hub fit in the rim. There should be no space. The center hole or hub is supposed to take the weight not the lugs. It is why uni- lug wheels seem to always open up and loosen up. The center hub hole is too big and puts too much on the lugs that are oval to begin with.
