Siren LP – Pink Compound

JConcepts hits the track with another weapon for the carpet and astroturf racing world. The Siren tire, shares styling cues from its successful racing sibling, the Nessi. Racing on artificial surfaces require a lot of stability and forward-bite and the design team went to work to substantially improve performance for deep nested turf or carpet surfaces. The new tire brings a new larger and taller sized 3D blended pin-size, pin-separation, and a lightweight and incredibly low-profile carcass.

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 represents a new compound for JConcepts, 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.

The Siren tire has already produced results on the racing scene. Paul Wynn, racing the JConcepts Turf Nationals in Enfield, Connecticut, in the 40+ 2wd modified class scored a difficult victory on the RC Madness outdoor astroturf track. Utilizing both Nessi and Siren, Paul went to the Siren during times when the surface was a little warmer and dirt underneath the track turned to dust and saturated the turf. The Siren dug into these sections with ease to produce more grip and consistency for long main events.
