Gokart,
Is it polished aluminum with clear coat that is peeling or is it chrome? If it is just clear coat, you can either sand blast it off (the easiest way) or you can use aircraft stripper. Then it's just a matter of getting someone to paint them for you. It is important to use a good quality clear coat because wheels are subjected to wet, salt, dust, etc., more than any other part of the car. After all, you don't want the same thing to happen again.
I'm not sure how to deal with chrome. If that is, indeed, what you have?
