Well, they've apparently changed something in the forumula. My back tire is doing better, but I hate the way it handles in the corners. Even mild leaning feels like I'm on Jello. A buddy with a Sportster put on Metzlers and had the same problem. I'm thinking about switching to Dunlop, but not sure which would be the best tread design for general riding. Don't care much for the new style tires (like the rear Metz on mine) with large patches of solid rubber. Guess I need to research this pretty quickly.
