I think that gray roadster actually has gray painted wheels, not black.
Whatever they did on that Grey one, it just doesn't look good.
I am extremely interested in how the black wheels look on a Roadster because I tentatively ordered them for a Radiant Red Sport model.
I think it will work with a glossy black wheel and also have the Carbon Fiber hardtop.
I plan on visiting Menlo Park for a few days to have fun with my car before it is shipped. If I don't like the black wheels, I am hopeful they will let me swap for the original silver Tesla wheels. But I am going to try it out in black first to see how it works.
