SBP wheels?

I bought these as sbp, tape measure shows 5x4, caliper/micrometer shows the same (no pic), so why do they not seem to fit?

Lug nuts do not appear to fully seat, same nuts used with my steel original sbp wheels, and the center hole is too big.

I was going to list for sale, I had my rear wheel off, so figured I'd confirm with a pic.
I don't want to sell if they're not correct.
