I just put on Mettzler ME880s replacing the old stock tires afer everything that I read here. So far they are great!!! Highly recommend. You will not believe the difference better/new tires will make to the ride. I was slightly concerned when I first jumped on the bike after mounting the tires since there was a little bit of a vibration I wasn't used to coming through the bike, but soon I realized that that was the feeling of tires with tread!
