It's getting time to change to winter tires on my E55 and I am looking to change from my Pirelli performance winter tires to a studless snow and ice tire. I realize I will be giving up the performance handling and will now be compelled to keep my speeds in double digits but was curious as to any insights on the snow handling aspects of the Blizzaks. I have read the reviews on Tire Rack but, as always, welcome first hand opinions from the Prime community.
