Winter tyres , silly question

Seen a lot of worth it / not worth it for the UK even down to the fact that you may have invested in a winter set of wheels and tyres but the chap behind you on the road hasn't!!!

Anyway , my silly question is the step and tyre size on the M135i is key to the way it handles , fronts are 225 rears 245 IIRC and the Winter Wheel and tyre offer from BMW are 205? am I stupid or will this compromise the whole car? surely if you wanted to keep the cars handling but improve in the colder months you would have the same size tyres but just winter spec?

saw that Autocar thing about Mich AP4's on Porsches and got me thinking as they point was that they come in 20 + sizes
