Federal comes with their Response tire which has been designed for use with either park or street riding. The center strip runs continuously which ads a faster roll speed and more control to the tire. A deeply cut directional tread enhances the grip capabilities of the Response tire even more. And lastly, the tire-tread tapers where it meets the sidewall for decreased resistance in grinds.
The sidewalls have been infused with nylon for much higher resistance to tears.
