Beskrivelse
High-tech tread for maximum traction
At the heart of the Rock Block is its asymmetric tread, giving drivers maximum flexibility when setting up their rig:
- Hybrid center structure: One side of the centerline uses solid tread blocks that widen toward the base and feature notches for extra biting edges. The opposite side uses split blocks that conform perfectly to uneven terrain and rock crevices.
- Zig-zag outer lugs: The outer lugs complement the support provided by the center. Deep recesses generate strong grip on dry surfaces, while shallow connecting bridges add stability.
- Intelligent sidewall: Massive side lugs are tied together by ribs, helping stabilize the tire during extreme off-camber situations and tight lines. The progressive pattern supports forward drive in any situation.
- Markings: For easy setup, the tires are marked directly on the sidewall with L (Left) and R (Right).

Molded in the legendary, ultra-tacky “Sticky Green” rubber compound, the Rock Block strikes an ideal balance of flexibility and damping to properly support vehicle weight.
