Studded snow tires are indeed great for ice, but they can actually reduce traction when the roads are clear because the studs reduce rubber contact with the road a little. Unless you are doing the majority of your driving on back roads that may stay snow/ice covered it’s hard to recommend studded snow tires when snow tires today, like Blizzak or X-Ice, give very good traction in snow/ice, but also great performance on cleared roads.
