I know that any "wax" will not last long with the heat that wheels generate with brakes, etc. Regular wax is too delicate for any type of longevity as it fails or melts at a fairly low temp.
You also want to avoid any type of chrome or metal polish as Viper factory wheels are clearcoated...and these type of polishes could damage the clear.
Treat them as you would the other painted parts of your car. I use the "Z" word (avoiding starting a war) polish on my car and wheels. According to tests like Guru Reports, it's the longest lasting product available. (A real plus on wheels) They are much easier to keep clean this way.
