I've noticed the same problem! As I recall, I did not notice the clicking until a few weeks after installing studded winter tires. My guess is that it's an issue that somehow pertains to cold winter temperatures.
I've noticed the sound while driving, while stopped at traffic lights, and also originating from my right passenger door assembly with the car turned off. The passenger door clicking is only noticeable when I open the door after returning home, after the car has been sitting outside all day the cold. I'd love to get to the bottom of this...
