Despite many negative reviews, ive been riding Conti gp 4000s clinchers, and dont have a single complaint. After 2,000 miles they are still in great condition, and will probably go for another 1,500. The compound offers excellent cornering, and grip in wet conditions, and the tires make the ride feel very stable. Not to mention the second to none wear on these things. Like I said if you rotate them I wouldnt be surprised if they go for 3,500 to 4,000 miles.
