I have two of these tires, purchased 2-3 thousand miles apart, moving the worn one to the rear. The rear tire now has about 4,000 miles, maybe somewhat more. The cords aren't showing yet but the middle 3/4" of tread is worn flat and some cracking has developed on sidewall. I will probably retire the rear tire (no pun intended) before it reaches its claimed life of 6,000 miles because of the sidewall issue even if the tred hasn't worn down to the cords. The front tire has over 2,000 miles and looks nearly new. All mileage has been on mainly smooth, paved roads. I've had three flats total. It's a fairly fast, quiet tire (I ride a dual 26" LWB bent)and handles rough pavement well (inflated to 85 psi). For loaded touring, I would trade some the the speed and quietness for a wider tire on the rear with higher rated flat resistance. For local riding, this tire has done very well and I may buy it again.
