jcoo, I understand what you mean, but we 've had pretty much snow last winters and I ALWAYS drove with normal tyres. My former M3 too. And IN the snow I could maintain 100km/h or more(braking distances sucks doh)on the highway where many other cars were doing 50/60kmh inthe slower lane. Maybe I am a lunatic dunno
This is me, no worries
