I probably have bad roads because in both 25mm and 28mm I kept getting punctures that needed plugging rather than being able to get sealed. Once both 25 and 28 got plugged and got another puncture, all within 1000 mileels or so, I was done with them. On positive side they rolled and felt real good. My new tire is pirelli tlr race which I have now used for almost a month and 500 miles. No single puncture yet but they do not feel as fast though.
