JConcepts 5.75" Rock Bumps 2.2" Tires (2)

The JConcepts Rock Bumps 2.2-Inch All Terrain Rock Crawler Tires are purpose-built, delivering aggressive performance and precise traction on demanding terrain. Featuring a large overall diameter of 5.75 inches, these tires offer excellent ground clearance for climbing over rugged obstacles. A narrow contact patch increases pressure on each tread pin, helping the tires bite deeper into uneven surfaces and maximizing control when it matters most.

Maximum Grip & Flexibility

The Rock Bumps tread design combines oversized pins with horizontal and vertical connector bars, creating a tightly engineered structure that flexes and conforms to the terrain. A solid center lug initiates forward bite, while relief cuts provide clean transitions to neighboring pins. Angular sidewall bars lead into a unique open-shield design, enhancing lateral grip and surface engagement. The narrow tire carcass improves flexibility, helping the tire wrap around rocks and obstacles with ease.
