It depends on what you want to do, and how much you want to spend. If you want to ride all the time when it is icy you could get some studded tires and use them just when you think it is needed. Or do what I do, have another bike with the studded tires mounted, just take the other bike sometimes. That's the easiest way to ride as much as possible.
With the studded tires you might want to ride on some lakes.
