Just a couple of pics of my k8 BT-15's after first day at Infineon at Novice (read scared poop-less) level. It is amazing how the look of the tire changed through the day. The A level riders tires looked 300 times worse. The experienced riders told me the tire is just "worked" but no damage. They also told me you can never get a tire hot like this on street. I believe them.
