I need your advice on tires.....

^ Agree 100%. The big problem with driving in winter is all of the people driving on the wrong tire. Either the temp is too cold for what they have or their tread pattern is all wrong. An all season tire is in the optimal range in only a very narrow condition - not cold enough to freeze water, not enough accumulation or snow packing. The very nature of winter is for conditions to change rapidly and severely. Those snow tires at home aren't going to do you any good when you're sliding backwards up a highway with an 18 wheeler approaching at 60 mph.
And when its the other car that has lost control and is drifting towards your car, the last thing you want to happen is for you to be unable to move quickly to avoid them. As the Tire Rack video I posted above clearly shows, evasive driving on winter tires has no equal. You will get around that curb, highway divider, tree, fence, etc. without hitting it.
