I think what might make this tough for midwestern states is that the snow doesn't stick around all winter. It's not unheard of to have 4-5 big snows that melt relatively quickly and most of the winter you're just dealing with cold weather. If you won't have a reliable snow pack you can guarantee you'll be driving on for three or four months it's hard to justify swapping out for snow tires or chains.
