Don't feel bad, I had mine for two weeks before I realized they were wheel covers. Looked again at the website and it does say "chrome clad" which I guess didn't register in my feeble brain.
Has anyone taken the chrome wheel covers off to see what the aluminum wheels look like? I haven't gathered the energy to do it yet and I'm curious exactly what they look like uncovered. Looking at the inside of a wheel from the opposite side of the car they appear to be cast aluminum. I'm wondering if they could be painted a gloss black and used without the wheel covers. Maybe with some black lugnuts and maybe a black center cap of some kind.
