Yes, there are other All Season tires that do even better in the snow but, you have to ask yourself,
How much snow does your area get statistically?
How much tire noise are you willing to accept?
How much MPG lo$$ are you willing to accept in the other 3 season, due to higher rolling resistance?
And more!
The reason I bring up these questions is because, there is a new breed of All Season tires that are heavily focused on WINTER traction over some other performance categories and meet the "Severe Snow Service Requirements".
Although these new tires seem to be decent A/S tires as well, they may not be right for you for the other 3 seasons.
