What would I have to do to get these rims to work?

Pro Comp Alloy Wheels Part 7005-8936 - Series 7005 - Flat Black Alloy Wheel by Pro Comp

These are sweet but I think I may need an adapter to make em work.

Does pro comp not make them in a 6x5.5 (139.7mm) pattern?

I think they do for the 17" rim, but not for the 18". That's why I'm wondering. I just dont know if theyll work.
