I've always had my winter tires on seperate wheels. In the past it's been steel wheels, but for my current car, I got a matching set of OEM wheels fairly cheap bc someone had custom wheels put on their car and didn't want the OEM wheels, so I bought them at a discount from the dealer, and had some winter tires put on. I couldn't imagine getting the tires on my wheels switched twice a year, I just get the wheels swapped. I used to do it myself, it's a bit of a workout to change four wheels, these days I get a shop to do it. Steel wheels aren't the most aesthetic, although my silver Subaru looked pretty good in the snow with 17" black wheels and some aggressive winter tires. Drifting...drifting...drifting the night away!
