Stance Picture with questions

[BP68]

Hey all, I found this picture, and it is exactly the wheel size/look I am going for. All I know for sure is that these wheels are American Racing Torque Thrust II's and they are 18" front and back. With Kumho Ecsta stx tires.

Could anyone guess the rim widths and tires sizes from these pictures? Mabye 255/55R18?

I also want to get the rear wheels aligned with the fronts, so I need back spacing info. I was thinking 18x8 or 18x8.5 fronts and 18x10 rears? The amount of side wall you see in these pics is what I want. Need tire sizes? Any suggestions or advice from experience? I have a ECE 4/6 drop kit. Thanks for any help.
