Very loud, bumpy awful tire. The car shakes when you drive. Dealer's response: "did you complete an alignment?" Which I did. Never again. True waste of money. No experience on snow and can't comment on tread.
I just got this car and do not know about the treadwear but I HATE the road noise that comes with them. I only have 1500 miles and I am trying to get another set of tires to replace these. My car roars at high speeds on lots of road surfaces with these tires. We don't have snow in Texas very often.
