When driving on a highway at 75, I constantly have to steer left or right, as car wouldn't just go straight, it slowly pulls to either side. And traction control kicks in at even slow speeds around bends. In simple terms, the car just feels wobbly. My last winter tire was Sottozero 2 that I was pretty happy with. But the new model is just undrivable. Is it because it is a taller tire (45 vs. 40) or because they are just really bad tires? Any ideas?

Are you saying that you've mixed tire models (i.e., 3s and 2s) - if so, are the tread patterns identical? Not saying if this is the case that it necessarily has anything to do with it, but it would make me wonder if it might.
Another thing that comes to mind, you've now got front tires and rear tires with different rolling circumferences, right? I wonder if this car expects them to be more or less equal; that is, within a margin that yours are exceeding. Nannies kicking in when they shouldn't made me think of this.
