JConcepts introduces the Siren tire for carpet and astroturf racing, drawing inspiration from the successful Nessi. Designed for stability, steering, and forward bite on artificial surfaces, the Siren features a larger, taller 3D blended pin design and a low-profile carcass. Its 2.2” bead mounting size makes it versatile across various conditions. The semi-circle protrusions improve side-bite while minimizing grip-roll.
