Snow tire suggestions for 2012 35d

Hello Fellow Bimmerfesters,

I am about to have snow tires installed on my recently-purchased 2012 X5 35d and I am in need of your feedback. I'm looking at either the Bridgestone Blizzak DM-V1 or the Michelin Latitude Alpin. Have any of you ran either of these tires on your X? If so, how did they perform?

I am in field sales and put around 50,000 per year on my X. I cover 5 states in the Northern Midwest so FEET of snow, awful ice and otherwise miserable driving are in my cards, in the very-near future! Any feedback is greatly appreciated- especially how either these or other favorite snow tires perform for you.

Thanks in advance,

John
