My Schwalbes are hard to get on & off. Practice in your home (or better yet at your bike shop).

Having said that, I need to do some practicing. On the other hand I haven't had any flats on the road.

They lasted about 8000 miles for me. This last time, I knew they were getting worn but I didn't realize quite how worn. I was amazed, with how flaky they were, that I hadn't had any flats.
