6V-PATTERN SHOULDER SIPE Two-in-One PATTERN DRAINAGEThe two center groove design canefficiently enhance superior wethandling and drainage ability.SHOULDER SIPEThe tire shoulder edge sipesdesign promote equaland long distance treadwear.Two-in-One PATTERNThe Two-in-One pitches are designed toreduce pattern noise andpromote comfort when driving.V-PATTERN“V” sub-groovespattern in the design,increase drainage onwet road conditions.
7The directional tire drainage is superior than non-directional tires, especially the main grooves that can drain water much better on wet roadconditions, The V-SHAPED pattern is designed to also assist the drainagefrom the tread to tire shoulder, improving how the tire displaces water.
9NS-20 is an elegant design without losing it's wild Performance. It is also a quiet, comfortable multifunction tire. NS-20 also adopted new technology such as Dual-Layer Tread, Micro Vent, Comfort Profile designed, and 5Pitche arrangement for low noise tire pattern designs.SUMMER TIRESPORT SERIESHANDLINGCOMFORTLOW NOISEDURABILITYDRAINAGEFURL SAVINGNS-20The 5 pitch design can effectively reduce the noise generated by the tire tread.

11The Initial Dual Layer Tread is shown below The Initial Dual Layer Tread is shown below. After using a tire for a period oftime (wear conditions depending on driver influence), then the soft sub-Layercompound appears.Take 225/40R18 92 W NS-20 as an example, the size groove depth is8.1mm, when the 1st layer tread finish wearing (About 5,000km), whichis half of the depth(4.0mm), then the 2nd tread will appear.
12Initial Dual Layer Tread Tire wear after a period of timecan still maintain the sameperformanceof a new tire.

19AS-1 Contact PatchThe Contact patch is the portion of a vehicle's tire that is in actual contactwith the road surface. It is most commonly used in the discussion ofPneumatic tires where the term is strictly used to describe the portionof the tire’s tread that touches the road surface. The term Footprint isalso used to describe this.

225 Pitches on RX-615ABCDEThe NANKANG RX-615 is not designed as a competitive tires, but mainly to be acomfortable tire. A comfort tire of course must also address road noise. The RX-615design features a physical characteristic called "Frequency Transformation“, to reducethe noise caused by the tire blocks. This method is used in the 5 different sizes placedIn RX-615, and using computer simulation of different sizes combinations to make thetire rolling noise generated varies frequency. The optimized tread design can greatlyreduce the amount of road noise from a tire.
