I'm due for some new tires and I 've been thinking about getting studded snows, but I"m not sure if it is worth it. Wanted to see what you guys were running and what your preferences are. I just went through my last set of tires in two years. I was hoping to get a little more out of them. Thought maybe if I did summer and winter tires I might be better off. So, what do you guys do?
