Rolling Diameter Question

Hi, I had a quick question. I've been looking into getting a new set of wheels. I have a 07 328xi and from what I have been reading if I want to run a staggered set up I have to make sure the rolling diameter is less than 1%. Now if I have a set of 18s and I run 225/40/18 in the front and 255/35/18 in the rear I know ill be okay, but MY QUESTION is if I have 18s can I run 235/40/18s all around or would my rear tires sidewall have to be less. What are my options? thanks a lot
