This has become my favorite tire over the past year. I use a Ride 25 on the rear and a Ride 23 on the front - providing a great balance between ride comfort, traction, weight and durability. I have been amazed by how few flats I've had with these tires. I've gone through about half a dozen of these and worn most down to the cords without a flat.
The rear tire tread seems to wear a bit quicker than I'd like, showing a red layer underneath the black, sometimes after well less than 1000 miles. The first time, I swapped out the tire when this happened, but since then I've just left them on. After several hundred more miles, I wore through the red layer as well, and I could definitely tell I was down to the casing. Surprisingly, still no flats.
Don't expect thousands of miles (particularly on the rear) - this is still a high performance race tire - but it is surprisingly durable considering its performance.
