Thin racing tires may be great for speed and agility. But they aren't so terrific when it comes to handling potholes, curbs, and the other flotsam and jetsom found on most city streets. The width of our Reflective Stripe Tires makes them ideal for urban riding, while the reflective stripe adds an extra level of visibility and safety at night. We carefully chose the color combinations to match our bike frames. The black with tan sidewall come on our blue and green bikes. The tan with tan sidewall comes on our white and orange bikes. They'll also nicely accent almost any urban bicycle. These Reflective Stripe Tires come standard on our PUBLIC M and D model bikes. They can be upgraded on any other PUBLIC bike for a small labor charge.
