After 11k miles, I noticed my Dunlop Winter Sport RunOnFlat had center wear, probably 2-3k of life left, but my front Elite 3 needed replaced. I had kept it at 41-43psi. I switched to the Bridgestones G704/709. I know, new shoes, but the flickability of MC tires are better. I知 glad I tried out the darkside, but I知 willing to pay more for better performance.
