If you have a doughnut spare, I would sell that, buy a cheap tire, and mount that on a steely and use it as a full-size spare. You could also mount snow tires on the spare rims and use those in the winter. I don't know how much snow you get in NoVA, but I know it can get pretty hairy in Blacksburg sometimes, and I would feel a little better if I had a good set of snow tires if I had to drive in that. The steelies will also keep your alloys out of the salt. They don't seem to use as much as they do up here in MA, so it may not be as important, but it's an option for your consideration.
