That was Deep Ocean's point: The reason Fisker offers a separate, 21" winter wheel is because there are no winter tires that will fit on the stock 22" circuit blade wheels and still fit in the wheel well. Fisker does have a custom 21" winter tire designed to fit the 21" winter wheels in the well. This is the $6000US wheel-and-tire package you'll see Fisker offer.
