You can also try some All-Weather set of tires (which are different of the All-Season tires), so you can avoid changing it every winter. I've used the Michelin CrossClimate2. Hope it helps.
All weather, all season, whatever you want to call them, they are the same catagory of tire. Can you install better 4-season tires than comes from the factory? Yes. Will it come even close to real snow tires in cold weather? No.
Why is this? Snow tires are soft rubber, the colder it gets the harder rubber gets so if you start soft you maintain the grip. You need a harder tire for hot weather or it wears out really fast. Anything for "all seasons" is a compromise tire.
Not having to changeover tires or a tire/wheel package is nice but there is a tradeoff in performance. Depends on how much performance you want/need.
For me, not having AWD was the con of the carnival and having a great set of alloys wearing X-Ice tires is good fix.
