Question Correct sizing for winter tires

The E60 OEM tire setup is usually 225/50/R17. For winter driving in snow, the narrower the tire, the better.

What is the absolute minimum snow tire width you'd recommend for a E60 xi: 215? 205? At what point is performance affected?

What about tire height? It would seem that the higher, the better, Is 55 too high?

Just interested in understanding the dynamics operating here for snow tires.
