I believe you have wrote enough for roght answer...

1. roll fender is nonsense. You said you have problem with front. Rolling fender is good only for rear...
2. is your trouble wheel arch or fender?

a) if it's wheel arch -> spacer will do the job
b) if it's wheel arch nothing but new wheel would help

however... according to numbers you have posted... let's have some math:

I have 205/50/16 on 16'' x 7.5'' offset +35 - no rubbing even with lowered front for 25mm

you have 225/40/18 on 18'' x 7.5'' offset +45 and you car is not lowered...
so... your rim is the same width and for 7mm closer to wheel arch (7mm more far from fender) but your wheel with that size of tire is bigger (diameter is for 26mm bigger and width is also plus 20mm). So... in my opinion your wheel is for 17mm closer to wheel arch and for 3mm closer to fender than my is. That means you more probably rub wheel arch that fender.

you have only two ways to go:

1.: buy spacers 5mm or better 10mm -> to be far from wheel arch for 10mm (if you have chance for custom size of spacer I would use 7mm spacer cuz there is still the chance you may start rubbing with fender not the arch this time)
2.: buy 225/35/18 tires -> to have the same diameter of wheel (only for 4mm bigger diameter than my ones!!!)
