JCO4137-02 JConcepts Bossman - green compound, 1.9" (4.19" OD)

The Bossman tire begins with the needs of performance-focused professionals. Its asymmetrical design means the left and right sides of the tire are not mirror images, offering different traction characteristics depending on orientation. The sticky green rubber compound delivers excellent grip and class-leading performance.

The center tread has a dynamic design meant to conform to rocks and flat surfaces. Micro-blading on the tread allows the tire to roll over small imperfections while maintaining bite on smooth or uneven terrain. The tread tops resemble cracked, dry desert earth—enhancing grip and realism.

The sidewall lugs can trail or lead based on how the tire is mounted, providing high-end pinch grip characteristics. The Bossman excels on tight trails and weather-worn flat rocks, offering top-tier fit, finish, and unique appearance for competitive crawlers.

It includes an open cell insert and fits standard and beadlock 1.9” wheels. A recessed JConcepts logo with inner hatching appears in multiple areas, alongside the tire name, part number (4137), and size markings (4.19” OD, 1.53” width) for easy identification and tuning.
