The Rock Bumps 2.2 are all-terrain rock crawler tires from JConcepts, sold as a pair of 5.75-inch-diameter tires in green. The tread is built for aggressive, precise grip on demanding ground. The large overall diameter adds ground clearance for climbing over rough obstacles. The narrow contact patch puts more pressure on each pin, so the tire digs into uneven surfaces and holds where control matters most. The tread pairs oversized pins with horizontal and vertical connector bars. The bars make a tightly engineered structure that flexes and conforms to the terrain. A solid center lug provides forward bite, and relief cuts give clean transitions to the neighboring pins. Angled sidewall bars lead into an open-shield design that improves lateral grip. The narrow carcass flexes easily, so the tire wraps around rocks and obstacles.
