The Nankang NS-20 features four straight wide grooves which improve tire drainage and maneuverability in wet conditions. New silica tread compound allows the NS-20 to have excellent grip.The two sub straight grooves on tire shoulder not only share the main grooves drainage, but reduce tread wear efficiently. The kerfs can reduce pattern noise cause by tire rolling. Sipes on tire shoulder reduce tire block rigidity, lower the noise form road, and increase comfort ability. Nankang design group designs NS-20 by 5 pitches computer simulation technology. This computer formula can reduce tire noise efficiently.
