No, spacers if anything might worsen it. Spacers will push the wheels out, and would only be helpful if you were rubbing against the inside, ie the suspension parts.

Your issue with a 235/40 on 8.5" and 38 offset is that

1) the wheel is sticking further out than it normally would
2) the 235/40 tire is 1/3rd" TALLER than a 225/40

I think it'll rub because I once ran a style 197 (oem sport wheel off the e90 328i) and that had a 8" front and high 30 offset. I too ran a 235/40-18 and I rubbed against the outer fender liner, right by the sidemarker. So given that you're running a rim that's 0.5" wider, I would think you'd encounter the same issue.

I would stick to a 225/40-18 up front and 255/35-18 in the rear. It'll look a tiny bit stretched but nothing to be overly concerned with. If you're set on running a 235/40, adding negative camber may help.
