Sheila Lankford - I've had a completely different experience in Fairbanks. My Blizzaks were fine the second winter when I swapped them out for other tires over the summer, but the second summer, I didn't and the Blizzaks had to be replaced come winter. A standard set of aggressive tread M&S tires (non-studded) lasts us six years, running summer and winter. The Blizzaks run summer and winter lasted two-and-half years. Considering they were more expensive than the M&S, they weren't worth it.
