Nankang Cross Sport SP-9
Nankang Cross Sport SP-9
Sporting an all-season tread design and optimized groove patterns, the NANKANG SP-9 is the perfect blend of performance, comfort, and safety to complement any touring sedan or CUV.
- Four circumferential grooves deliver improved handling and promote water evacuation
- Optimized siping pattern enhance wet-traction and control
- Angled tread blocks support lateral grip for exceptional handling
- Lateral grooves dissipate water to reduce the risk of hydroplaning
Four straight wide grooves enhance tyre drainage efficiency and manoeuvrability on wet road condition. The optimized evenly thin sipes reduce road impact and improve the comfort when driving. Center rib design to enhance steady handling. The 5 pitches computer simulation technology decreases noise at high speed.
The European Union, under CE 1222/2009, has mandated that all tyres manufactured after the date of July 1 2012 for cars and commercial vehicles include standard EU Tyre Labels classifying them by three performance characteristics:fuel efficiency classified from A to G,wet grip classified from A to G, and noise emission in decibels.
Categories of tyres unaffected by this regulation include: retreaded tyres, professional off-road tyres, racing/sports car tyres, as well as certain types of tyres designed to improve traction such as studded tyres, T-type temporary spare tyres, tyres for cars built before 1990, tyres with a maximum allowed speed of 80km/h, tyres for rims with a diameter less or equal to 254 mm or greater or equal to 635 mm.
This label is intended on one hand to promote economic and ecological efficiency in traffic, as well as increase road safety, and on the other hand to help consumers select appropriate tyres by ensuring a certain degree of product transparency.
Nevertheless, the label has been criticized for only showing a very limited number of characteristics. Professionals argue that tyres have many more features that are important and relevant to road safety, including but not limited to aquaplaning properties, driving stability, service life, product properties on wet and dry roads other than wet grip, properties on snow.
Tyre manufacturers suggest that the test results from various institutions and industry magazines should remain a very important source of information for the end consumer, because they focus on and rate a wide variety of tyre properties and features.
