I think running winter tires is a better improvement in safety for the buck than getting expensive all season tires (jack of trades master of none). And they make your expensive set of summer tires last a heck of a lot longer. A second set of wheels is more convenient and adds cost, but it's a much better investment than go fast (marginally) parts, a stereo, Ipad in the center console, and a bunch of other stuff
