Nankang Noble Sport NS-20 ( 215/40 ZR17 87W XL )

NS-20 High-Tech Product

The NS-20 is Nankang's new high-tech product designed for the highest demands. It combines improved handling and low rolling noise through a new silica tread compound, excelling in wet grip, exceptional cornering stability, and high mileage.

Straight, wide tread grooves: The four straight, wide tread grooves enhance the tire's drainage and maneuverability under wet road conditions.

Straight, deeper tread grooves: The two straight, deeper tread grooves on the tire shoulders not only support the drainage of the main grooves but also reduce uneven tread wear.

Small lateral notches: The notches can help reduce rolling noise.

Tire sipes: The sipes on the tire shoulders reduce the stiffness of the tread blocks, decrease road noise, and increase comfort.

The Nankang design team developed the NS-20 using 5-pitch computer simulation technology, and the new pitch sequence has proven effective in reducing noise at high speeds.
