This is a set of two Axial 2.2/3.0 41mm Hankook MT Rear Tires, and are intended for use with the Axial EXO Terra. The EXO features realistic, officially licensed Hankook Dynapro MT tires that perform as good as they look. The rear tires are wide (41mm) putting the power to the ground with enough traction to keep the EXO firmly planted, while the internal ribbing helps reinforce the sidewall to prevent it from folding over which keeps the tires working at peak performance.
