If I were you I would do 18x10 and get your offset around ET45 (either by getting the correct wheel or using spacers if need be).
At the end of the day, there is very little to be gained by going beyond 10". I'm actually considering doing 9 or 9 1/2 on my next set of wheels. I run a 265/35 on my 18x10, but alot of guys run Turbo size rears at 285/30. Even if running the 285/30 you're not going to put any appreciable amount more rubber on the road by going to a 10 1/2" or even an 11" wide wheel.
I can assure you that car below has A LOT of rubbing going on.
Also a 275/30 on a 11" wheel will look stupid in my opinion. The tire will stretch out too much. You will have a big lip on the outside and inside of the wheel that has no rubber to cover it.

Stick to a 10" wheel on the rears.
EXACTLY! I coundn't say it any better. That's what I meant earlier by the lip sticking out 1-2mm from the tire. IT'S BAD for the tire too. Not good for the steel belts within the tires. You will also have fast wearing down on the center as I did until I you put the correct tires on that rim. And then you would get serious rubbing when you hit pot wholes. That car is also lowered in that picture. If it wasn't, you may have a better chance with the proper tires on those rims. Stick with 18s.
