I am debating on whether or not to get winter tires for my 228i Xdrive. I live in Vancouver, BC. Unlike the rest of Canada, it only snows around 2 to 3 times per year, and the snow melts pretty quickly (2 days max).Although my 2er is my secondary car, I will take it out when it snows. So I am concerned that the stock all season tires will not provide enough grip when I need it. Last winter, I did a big slide in the middle of a busy intersection. It was not fun.

If I should get winter tires, what tire size should I get? And what kind of rims? Do steel rims work? My car has M sport package but not track handling package (no big brake). My stock tires are square 225/40-18 Pirelli P7 run-flats.

Thanks in advance

Edit: Because how rare it snows here, most people don't have winter tires. If there's an emergency and I am able to stop in time, the person behind be will not be able to stop.
