I wish the black wheel fad would die along with the carolina squat and flat brim hats. This is coming from a guy that ran black wheels on a white tacoma. They look ok, but I like an aluminum rim to contrast the black of the wheel. That wheel in gunmetal grey would be glorious. My .02.
PS- OP, you have a beautiful truck. super jealous.
I did that wheel and had the black powder coated silver. I almost went with gunmetal gray. I also removed the chrome strips on the sides.
