I would think wheels tested at 1750# and twice that for cornering fatigue would be more than adequate for just about any small body car.

Once again I have the SAE test in PDF if anyone wants to see it.
Which standard states this, SAE, TUV, JWL, etc.

The problem with this point of view is that inside a given forging envelope the spoke cross section does not necessarily have to be exactly the same shape just a different thickness. The curvature, radii and other subtleties can also change. Thus again right back to my point about having a engineer in the loop.

I was not aware that multiple companies doing different parts of a wheel take part in the responsibility for the safety of a given design. Could it be different for 1 piece vs. multi-piece wheels? It shouldn't be regardless of who makes what THE wheel manufacturer should (and does I believe) assume ALL responsibility for the safety of the final complete wheel.
