Hi everyone, I am a new owner of a 2009 M3 sedan. This is my daily driver and I think I need to start thinking about the winter and what I should do. Currently I have the 19’s on the car but I am wondering if I need to change the wheels and ties for winter. If so, what size should I get? I am totally new to this so I am not sure what I should be looking for so I am hoping someone can point me in the right direction. Any help you could give me on what I should get would be great. Thank you!
