Just wanted to drop a quick note on snow tires.
I picked up these
Nokian Hakkapeliitta R5 SUV
These went on a second set of 20" wheels that I had previously. The circumference is about equal to my Platinum's 275/50R22 wheels/tires.
Happy to report that they are super quiet snow tires, and I ended up having almost the same efficiency/mileage that I had with the 22" tires.
