215s are usually better for winter tires on the cars, although its so little a difference it might not be noticeable. The theory i that the smaller contact patch means same weight on smaller are which helps traction. The narrower tire is also less likely to float on snow and slush. I've owned 225s and 215s and haven't seen any significant difference, so cheaper is better in my book.
