How long have you had them? I have about 7k miles on mine and so far, so good. I will check to see how they perform in snow this winter when I hit the slopes

For the original poster, just so that you know...the OEM Bridgestone Turanza isn't any better than the Diamaris in terms of noise. It started roaring like crazy after 20k miles and the set only lasted 30k miles before I replaced them with the aforementioned Pirelli.
