This is my first BMW and a RWD and I have a set of Michelin Alpin PA4 winters ready when it does snow. However, I've been pleasantly surprised how well the MPSS have been performing in my city with 19F mornings and nights.

I believe this video.
That's exact the same 'feel' I had before I changed mine to winter setup.
At least around 30 F, PSS felt much better and gripper than Blizzak LM on dry road.
Although, there is good chance that PSS may crack in lower temperature.
Also, if there is any sort of moisture/precipitation, summer tire is downright dangerous.
I find this test video pretty interesting.
Key point here is "at low speed, there is not a big difference in traction between non summer tires".
Key is LOW SPEED. no matter what tires you have, if there is snow, slow down.
