Introducing the Nitto NT-01, the pinnacle of Nitto Tires technical excellence. The NT-01 is a D.O.T. approved competition radial with an asymmetrical, non-directional tread pattern optimized for dry racing conditions. Beginning with a tread depth of 6/32", the NT-01 can be shaved to 4/32" to reveal a "slick" tread surface with two circumferential tread grooves. The NT-01 features a racing-inspired tread compound formulated for on-track performance to deliver extreme cornering power for fast and consistent track times.
