Fitting 2012 Jeep Wrangler wheels on a C5

[KFC.ONE]

I realize this is not everyone cup of tea but I am just looking for technical info if anyone can lend a hand.

Came across some 2012 Jeep Wrangler Unlimited Sahara wheels in size 18" x 7.5".

They are a 5 lug 5x5 pattern.

What do I need to make these fit on a 2004 A6 Avant (C5) that currently has 215/55/16?

I know I need adapters but how about offset?

Best tire size to run with no stretch?

Best tire size to run with a little bit of stretch?

Any info is appreciated.

What is the off set of the Jeep rim?

Isn't the bolt pattern wrong?

I think that is the main hurdle. I'm not sure of the offset but I guess I was looking to find out here that if I had the offset the only thing I'd need is the correct width for the adapter.

It is, but that can be corrected with adapters.
