We live in Wisconsin and have in the past tucked the bike away for winter. With our Wagon now surpassing 3,000 miles I feel like it is officially broken in and well used. I no longer cringe if I scrape against a curb or worry about other wear and tear. So for this winter I decided to shop for some studded tires. They aren't cheap and I did a lot of price comparison shopping both to get the best deal and share with other Rad owners. I plan to post my thoughts when I get mine installed but for other RadWagon or RadCity owners here are some good options (Sorry Mini, Rover & Runner owners, perhaps someone who owns those will chime in too!)
It's worth noting that the stock tires on the Wagon and City are 26x2.3 and Rad wouldn't give me a definite answer on how narrow you can go on the stock rims. They only stated, "Plus or minus a little could work, but we've only tested them at 2.3" and to contact your local professional bike mechanic. Obviously you'll start to have clearance issues if you go wider. Since
I am my appointed professional bike mechanic I made the decision to try out some 2" tires. I was slightly concerned about clearance on the 2.35" wide Kendas below but I imagine they would have probably worked.
It seems that Schwalbe and Kenda have the most affordable studded tires as studded tires can easily reach into the $100's per tire.
I purchased the Schwalbe Marathon Winter Plus HS 396 Studded Mountain Bicycle Tire 26x2 - Wire Bead on a listing that had limited stock on Amazon.
Here is the link in case there are any left. I paid $62 per tire:

It appears that there is a slight variation between the two with one being the winter "plus". More info here:
