I work at a car lot and we had a newer Trailblazer that was a dark green. It had the Black Chrome Boss 318s on it. They looked sick. I was going to get the 24" Boss 313s in the regular black coating cause my Yukon is Black, I thought it would look great. I had a change of heart and decided to go UP, I mean 6" up, I live in Oregon and we have some real pot holes that tore the 18s I had on my old car. I didn't want to spend $2000 plus and bend a wheel a month later.
I guess it depends on the color of your car. I know they will look good if your car is: white, black, dark green, or grey.
