And you think the wheels and tyres look small now?. With black wheel arch moulds it'll look like you need 44s to fill the voids. That or Jaws took two bites out of it.
There are probably a few Photoshop capable people on here who could take that photo and change the colour for you to look at.
If you do decide on black then get them done properly so it doesn't look like you bought unpainted ones and were too much of a tightwad to paint them.
