Competition Proven. The NT01 is a D.O.T.-approved dry competition radial designed with the weekend road racer in mind. The compound was developed to provide the best balance of traction, consistency, heat cycle performance and longevity. The sidewall construction is optimized for sharp steering response, accurate feedback and increased driver confidence. For those that demand maximum dry performance, the NT01 can be shaved from 6/32 of an inch down to 3/32 of an inch to reveal the professional road-racer and the track-day enthusiast.
