25 years up north and all rear wheel drives. I like tire chains. Your driveway can be meticulous but that isn't where you're gonna get in trouble usually. 4x4s for the last 15 and I still need the chains but I've found a couple 5 gal buckets of beach sand gets us through those icy mornings on our hilly driveway. Just enough salt with the grip and the price is just right.... good luck!
