I've had the stocker,the SE 180, and two of these Metz. This is a very good tire with average wear. I ride two up most of the time so I think that wears the tire more. I got about 6500 miles out of the last one and that seems about normal.
I installed them myself and it is pretty tough but a little work and its on. New tube and Dynabeads and its sticky and stable. I run the air pressure recommended from Metzlers website.
I'm really impressed with the front tire. It has around 10,000 miles on it and it looks brand new. No sign of the terrible cupping that showed up on the stock Dunlop. Can't really tell the width difference from the SE180.
