When I had one bike I had thought about buying a second set of wheels but didn't know how advantageous stuff snow tires would be. But then, the snow melts quickly here. However three and four years ago we had snowy winter's with months long icy patches. So I didn't ride. When I bought a new bike two years ago, I bought suomi nokian w106s for the old bike.

Knowing what I know now, I would but a second wheelset and mount studded snow tires on it. Then I could swap tires fairly quickly. I really wish I would have done that.

Mounting and recounting tires is too much of a chore, but swapping wheels makes it easier, and I would do it as weather demands.
