I've been riding Gatorskins since 2012 and won't use anything else. I change them once a year, even it they still have the thread indicator showing, and I've been getting anywhere between 7-10,000 miles on a set. I do a cross state bike ride every October and change the tires the day before the ride. Last years tires lasted me 11,450 miles. Since 2012, I have had one flat caused by a puncture and one flat caused by a tire failure (leak at the base of the valve stem). Love those skins.
