182 - Wheel and Tyre Sizes

[Dredd]

I've just bought a FF 182 which has the cup pack 16" wheels with 205/45/16 tyres. I was wondering what my options are for wheel sizes - diameter, width and offset, along with options for tyre widths and profiles. I've had a look around but can't really find a guide or such with the options, so can anyone help me with this info please? Also does anyone know the width and offset of the wheels which come with the FF 182?
I think I want to fit OZ Superturismo's with Yokohama AD08R tyres, just not sure on what diameter, width and offset for the 182 and also what width and profile AD08R's to go with them.

Thanks in advance for any help.
