I'm ready to buy some new wheels for the rig and was wondering on what I should look for? I really like the black wheels, nothing shiny that I have to clean. I want to run 16x8 so that I can swap tires from my cruiser to my truck if needed. Is there a certain backspacing that I have to have and what is wheel spacers, well I assume they add space between the wheels and the brakes so I guess my question is, do I need them and if so, where do I get them?
