Aftermarket wheel and Tire Size

[P100DHG]

I am not going to lie the factory five replica wheels aren't my favorite. I don't mind them but Im not in love with them.

The Factory Five wheel specs taken from their video are:

18x9 w/ 24mm offset / 6” backspace
18x11 w/ 12mm offset / 6.4” backspace
255/35/r18
315/30/r18


I am strongly considering this in Vintage Silver:

I am lost in the specs... I would get the 8" wheels for the front and the 10" wheels for the back.

For the front there is one Option
VN51088012400 - 18x8 w/ 0mm offset and 4.50 backspace - This would have a 265/35/r18 Perilli P Zero Trofeo R

For the rear
VN51081012400 - 18x10 w/ 0mm offset and 5.5 backspace - This would have a 295/30/r18 Perilli P Zero Trofeo R
VN51081012412 - 18x10 w/ 12mm offset and 5.97 backspace - This would have a 295/30/r18 Perilli P Zero Trofeo R

My concerns:
- Rear tire width... Is it adequate?
- Will the front wheels stick out with a 0 offset? Do I even have this concept right?
- With a 12mm off set in the back on a 10" is that the same as the offset on an 11" wheel?

Ultimately I want to know will they fit (front and rear) and what rear combo should I use?

Ive watched youtube videos and still can't seem to grasp this concept. Thanks for your input.
