The same 255/35/18 tire will be wider when mounted on a 9.5" width wheel compared to a 8.5" width wheel. I don't think at +45 the 9.5" wheel would fit at all, even with no tire on it. I think it will touch the strut. Remember offset is measured from the midpoint of the wheel, regardless of width. Look at how close it is already... going to 9.5" with the same offset moves the inner rim a half inch towards the strut. There is maybe 1/8"-1/4" there with the 8.5" wheel.
Michelon's PSS 255/35/18 is rated for an 8.5 to 10 inch wide wheel. You can just look this up right on their website. Part number 07807

8.5" is on the narrow side of their recommendations, but gets quite a bit of tire under the front end of the car. Yes, sidewall stiffness is negatively affected by leaner to the narrow side on wheel width, but I don't feel a significant difference coming from 235/40/18 Dunlop Z1 on the same wheels. They're both lightyears from the runflats.

I'm a big boy. If I wreck a fender I'll let everyone know, but I've driven it enough now to feel pretty comfortable.
Do you have any added camber?
