Paint. My rallye rims gloss black?

My advice is not to paint them black, they would look tacky.
That goes for body color or even chromed.
Like abodyjoe says, they don't look right unless they are painted as original with black on the back and silver on the front.
The car would look good with an aftermarket wheel on it though, but at the end of the day, it doesn't matter what we think, it's your car............
So, do what you want!
My opinion FWIW.
