The NT555RII is a D.O.T. compliant road race competition radial designed with the muscle car racer in mind. Using the same computer designed tread design as the NT555R, the NT555RII has been thoroughly updated to handle the task of road racing. Construction modifications were made to improve cornering feedback, controllability and stability. The tire comes molded at 6/32" to reduce tread squirm. The NT555RII is recommended for competition use.
