Rear: 8.5x18 ET 37- Tire size 255/35R18

For winter I run a set of style 44 wheels which has an ET of 47 and I run tires of the size 225/50R17.

I ran these last winter and they fit, the fronts come pretty close to the strut but they clear just enough, for the rears there's plenty of space and I don't like how far in the tires sit in the wheel well.

I'm trying to figure out what size of spacer I would need to bring the rear tire out to where my summer tires sit.

According to the offset calculator the rear set up of the wheels have a difference of -4MM and according to the tire size calculator the tire width difference of 27.9MM.

If my calculations are correct and I remove the 4MM from 27.9 making it 23.9MM would it be safe to assume that I can throw a 20MM spacer which would bring the tire out to be almost as close as my summer wheel would sit?

Thanks for any input guys.

I'd go 225/45/18 square for winter tires

Or perhaps

225/40/18
