Tire/wheel question

[Sublime302]

I have talked to a few guys about tires and wheels. But tried searching to find out the largest/most preferred sizes of tires/wheels/ offsets to STILL be able to rotate the tires.

I want 20" wheels like PhuckPhace's ride.

So do i get 20x9 or 20x10's all around? also what offset will make them look nice like the offset on Phuckphace's car? I use his as a reference because its perfect stance and offset lol

My car will be white. Im thinking of some dark grey or matte black wheels. ideas?

thanks for info and help guys. im a NOOB to the s197's lol
