When I bought my studded snow tires, I ended up buying a whole new set of rims as well. An added benefit with purchasing another set of rims is you can swap them out yourself instead of waiting in line at the tire shop. Here in Anchorage, it's about $40-60 dollars each time you get the tire shop to swap out tires.
Before that I used to drive all year round with stud-less snow tires like Blizzaks. When you have snow on the ground 6-7 months out of the year, it wasn't worth the hassle to change over, plus I never drive more than 6K miles a year. I would have probably gotten a few years before needing to replace them.
Switched to snow tires yesterday, and it's snowing today 🙂
