The Nitto NT01 D.O.T. compliant tires are competition radials for dry racing on road and track. They are made of a special racing compound that balances traction, heat cycle performance, longevity, and consistency. High modulus rayon carcass, body ply construction, and steel reinforced sidewall ensure these tires retain their stability under extreme speeds. Large shoulder tread blocks provide a large surface contact area for better handling, cornering, and traction.
