I assume they are either painted or cleared underneath the black paint? Aircraft stripper will take paint off, but down to bare metal. No way to stop at the factory finish. And it's nasty stuff!
Having attempted to strip painted wheels myself-don't. Find some place to strip them for you. Then you can have them cleared if they're bare aluminum, or powdercoated the color of your choice.
Factory wheel paint is very, very thick. Even using aircraft stripper, it probably took me 50+ hours to do a wheel. Take them and have them dipped.
Wait-did I mention to not try to do this yourself?
