An Extreme Performance summer tire specifically designed for Club Racers participating in Autocross, Time Attack, HPDE & Endurance Racing.
The tires were developed for those that demand the highest level of performance..
Like most other motorsports tires, these are not intended to be stored nor driven in near freezing temperatures.
The Nankang CR-S asymmetric tread design is engineered specifically to increase rigidity to provide extreme levels of grip while providing direct steering response.
The aramid reinforced sidewall provides precise and responsive handling, while providing consistent performance.
The circumferential grooves evacuate water for improved traction and handling in the wet.
The CR-S is engineered with experience from Nankang Motorsport department’s racing tire concept. Each tire compound is engineered with enhanced formula for extreme levels of performance.
 
Break in procedure for Nankang tires prior to hard track sessions (racing or otherwise)…
.
The Nankang AR-1, CR-S, SL-1, and NS-2R will greatly benefit from an initial “break-in” heat cycle, (commonly called “scrubbing in”) before the tires are pushed, for better performance. Set cold air pressure at an adequate psi to handle the weight of the car. On track, gradually increase speed subsequently for a minimum 3-4 laps, not to exceed 85% capacity*, followed by an off the car cooling period of not less than 24 hours, which will result in a much improved tire life and on track performance for future sessions.
If this procedure is not possible due to losing on track sessions – PTS can heat cycle your tires prior to shipping them to you, which will reduce (not replace) the break in procedure required for AR-1’s and CR-1/CR-S models.
This is a proven procedure to enhance and improve your on track experience, gathered from many years of our own racing experience and track events, as well as the many experienced drivers we have worked with over the years.
*2 – laps 50%, 1 – lap 75%, 1 – 85%, 2 – cool down laps 50%
 
*Caution: The Nankang CR-S is recommended for competition events only.
 Allow an extra day for shaving or heat-cycling.
