Winter tire sizing

I have a 2023 BMW I4 EDrive 40 w/ Msport and Msport brakes. The stock size is 245/40R19 on the front and 255/40R19 on the rear. I'm shopping for winter tire packages and there are a few different size options for the car. My question is can I go to a 225/50R18 or 245/45R18 (which are both OE options) all the way around without issues or will I have clearance problems with the Msport brakes? Also, any other thoughts would be appreciated.
