* Precision machined blue-anodized 6061-T6 aluminum wheels ride on rubber-sealed ball bearings. * Rubber tires absorb bumps and keep the tires in contact with the ground. * The tires and wheels allow you to hold longer and more controllable wheelies. * Easily bolts directly onto Traxxas wheelie bars. * Replacement rubber tires are available separately, and they mount on the aluminum wheels and the stock nylon wheels.
