True, but a pressure vessel isn't usually loaded in the same way a wheel is.
However, you point is taken, a stamping could be designed that would work
without the spokes.

That's why I thought of spin forming, which would require a new design
driven by the manufacturing method. You could not possibly spin the spoked
design.

The more I look at the concave wheel, the more I think it is a completely
different design from all of the others. The concave wheels are assembled
in a fashion similar to the spoked stamped and the convex wheels. The
concave design doesn't have the second rim that the welded, stamped, and
convex have.
The spoked stamped design has two rims, one that the vertical flange is
riveted to, and another press fit onto the inner wheel to which the rubber
tire is vulcanized.

All of the concave wheels I have seen are the same on both sides. I have
photographed both sides wen ever possible. However, I can't see the weld
joint you speak of. I don't think they really needed it. If the two halves
were pressed into the tire with a suitable spacer for the bearing, the
bearing caps would hold the assembly together axially in expansion and the
spacer or wheel inside flanges could prevent inward lateral movement. The
press fit might be enough to prevent the tire from slipping, if not some
sort of internal lug would stop that.
