Designed in the industry standard 2.2" bead mounting size, the Siren is very versatile and has shown to work in many natural and artificial conditions. The semi-circle protrusions, unique to the Lockness, Nessi, and now the Siren are included in the center section of the tire and on the sidewall area. These details are important, and the low semi-circles improves side-bite but also minimize grip-rolling instances associated with normal pins. The pink compound is a medium soft material with good wear characteristics. The rear tires include open cell inserts making them a complete set ready to mount, straight out of the package.
