All you have to do is make sure you mask the tires...also it wouoldnt hurt to skuff the rims with something along the lines of 120grit and up and then use some scotch bright to take out any scratches from the 120..this will help give the paint something more to bight into..also if you can find some get some lexan clear coat if you put this over the color you want not only will they be nice and shiny but it creates a nice protective layer over the paint and wont chip as easy....
