You should run 225 45/17 square. In winter you need more sidewall compliance, not less.

If you don't need 18" rims for brake clearance, running them is profoundly counterproductive. Not only is the wheel/tyre combination heavier, you have far more risk of damaging a wheel if you hit a pothole, etc. This liklihood is far higher in limited visibility in winter with reduced hours of sunlight.

Honestly I don't even run 18's in summer, as my summer tyres have more than adequate sidewall stiffness.

17x8.5 in summer & 17x8 winter is almost ideal on our heavy cars with no real power. Everything else is just posing.
