1/10 Rock Block 1.9" Tires and Inserts Green Compound (2) (JCO4054-02)

Rock Block 1.9-inch tires with inserts for 1/10-scale crawlers are built to deliver dependable grip on rugged terrain. The asymmetrical center tread is clearly marked with left and right orientations, allowing drivers to tailor the setup. A three-block center pattern blends a solid lower block with a split upper block for adaptable climbing and trail performance, while outer lugs zig and zag to bite on dry surfaces. Open-cell inserts are included, and the tires are designed to mount on standard 1.9-inch wheels with an outer diameter of about 4.75 inches for versatility on popular rigs.

These tires use JConcepts sticky green compound to balance flex and traction across challenging trails, with a continuous thickness carcass for a clean profile and reinforced sidewalls with wear bars for durability. The open-cell inserts support the ride and help maintain a consistent feel through tight climbs, making them a solid choice for 1/10-scale crawlers that need reliable grip and long-lasting performance.
