This is a pair of two AKA Racing Vektor 2.2 Rear Buggy Tires. These tires do not include foam inserts. The VEKTOR tire features a low profile tread design which is ideal for hard packed indoor and outdoor tracks. The directional tire design allows you to choose between mild or aggressive handling characteristics depending on which way you run the tire. The carcass design, lug size and lug spacing have been designed to provide a good balance between tire wear vs. traction, delivering a great value to the racer.
