Just picked them up today and I had a 250 Km drive to test them on a dry pavement. That explains the no rate in the snow, wet and treadwear section. I like the thread, it looks aggressive and well directed to evacuate the water and the slush.
Since I was driving on dry pavement, I didn't find them to be more noisy than normal.
I live in Montreal,Quebec. So the winters are pretty rough around here. So hopefully I will write a positive review this spring about the Altimax.
