I am driving my '04 330ci in the snow for the first time this year (GF's 330xi is gone).  I needed winter tires.  Several on this board -- and many other people -- recommended Blizzaks but I was buying too late to get them.  I bought Toyo Observe Garits.  Picked them up yesterday in a snowstorm here in CT.  They are phenomenal.  I was passing other cars on the road, including SUVs and little front-drive things.  I took the car out last night after it had been snowing for about 8 hours just to see what the world looked like under a blanket of snow.  This morning I had to drive north about 20 miles and temperatures were in the teens.  There are plenty of twisty, hilly roads in CT and they were largely snow-covered but I had no trouble.  I chose to drive up several very steep hills just because I could.  Unbelievable.  This is my unsolicited and unpaid endorsement of Toyo Observe Garits.
