I have been DYING to see black painted Sahara wheels (as I try to talk myself into a Red Sahara with a black top).
I went over to a different Jeep dealer yesterday (River Front in North Aurura) to see what they had on the lot (not much). But while I was there...I really studied the Sahara wheels. The spokes could easily be painted while the outer rim/lip is left silver.
I've also been looking at different tires that don't really impact the overall size.
Duratracs come in 275/65/18. Not sure if they would rub or not.

If I knew photeshop better...I would black the rims out to see how it looked.
