Bought these tires with a threat of snow that never happened. Now we are having a snow/ice event that is rare in terms of volume of snow for Portland. These tires have been fantastic in the snow and better than expected on the ice. I've always used studded tires for winter tires and the Blizzak's are the first studless snow tire I've run on snow and ice. They are well worth the investment. The Altima's CVT transmission requires a feather touch with the throttle in bad weather conditions, and these tires have handled everything extremely well. Starting and stopping on hills, no problem. Driving on packed snowy roads covered with freezing rain on top, no problem. Can't praise these tires enough. Just buy them!
