Winter tires need winter wheels. Especially with the mandated onset of Tire Pressure Monitoring Systems, it is far less expensive in the long term to have an extra set of wheels on which your winter tires are mounted than to pay some one at least $20 per tire twice a year to switch the tires onto the same wheel. But what to look for in a winter wheel?
My best advice is always the least expensive, most simplistic wheel that you can find. It used to be that a steel wheel was the automatic choice for people running winter tires. They were inexpensive, and hard to ruin, so they fit the bill nicely. Nowadays, with steel prices running high and the demands of today's high performance vehicles' handling and braking potential, alloys are a much more practical choice. Also, sometimes they are your only choice, as they offer more clearance for today's larger brakes. They don't rust, they clear large brakes, and they actually look decent on the car. However, they don't have to be expensive.
Dependent upon your car and its needs, I would suggest taking a look at the Sport Edition or Elbrus wheel line. Their simplistic, classic designs make them easy to keep clean and maintain properly.
