I have not tested this tires on snow/ice yet but so far they are great. Very confident in a recent heavy rain storm. Excellent traction a steep gravel driveway.
I was amazed at how much grip these tires had recently on a road (80 km/h speed limit) covered in wet leaves with temperatures around freezing.
Equal or superior to stock firestone tires in dry conditions, road noise and comfort.
Have not had long enough to comment on tread wear.
