answer:I haven’t used snow tires in decades. Literally, “decades”. And for most of my life I’ve lived in climates and around roads similar to yours, I’m sure. (Michigan, Wisconsin and Connecticut, for the most part, though the cars I drive are generally lighter.) This year I helped to fund a Kickstarter project for ZipGripGo traction aids that you might also find useful as a way to maintain your all-season tires and forgo the hassle of snow tire changes. I haven’t tried them yet, since they were just delivered this summer, but the videos have convinced me of their utility and value.
