Just had mine changed a few days ago....as daytime highs have been reaching the low to mid 20's which are unseasonally high.
Looks like that I will have to get new winters next season as a couple of the tires have bulging sidewalls (due to the cords???)....still lotsa tread after lasting three winters.

I am guessing that Nordic Wintertrac cords are easily damaged as all tires have some sort of bulging varying from slight to moderate.
