Hello to All. I'm quite new to this. I bought my first BMW in July and am loving it. Quite a different ride compared to North American cars. I do have a question and not sure where I'm suppose to ask it. It's regarding my tires. I live in the lower mainland of Vancouver and we do get some snow. How will my car perform in the snow? Will I need to get snow tires? If so, just for the back or all 4's?
