It's your baby. Do what you want to it. If you are just unsure that you will like it, plasti-dip the wheels rather than paint them. From what I understand, it's quite easy to remove of you don't like the look, no harm done. If you do, move on to a more permanent solution.

Do not perform any mod for looks alone, mod for function. I promise you if you plan your mods to improve function, you will have a Jeep that "looks" the way you want.
