Black wheels have been a thing with the younger set for at least 5 years now, maybe 10. I agree with Michael, never liked them black. But I don't like chrome wheels either.
A couple months ago, I helped my son paint his beat-up Suby wheels black. Sanded them down by hand mostly, used an orbital to clean up the corroded spots. Stuck playing cards around the rim by deflating the tires for masking. Primed, then black, then 4 coats of clear. They came out really nice, and he's happy. But not my favorite look, they looked better silver.
