These tires were installed less than 1 month ago, so I can't testify to their longevity. However, I am very impressed so far with their performance. Since installing, the car has been driven regularly in rain/snow/ice weather conditions. These tires provide excellent traction and handling on side roads as well as the interstate. For driving in wet/winter weather, I recommend these tires. As for treadwear and longevity...only time will tell. Stay tuned!
