Nankang AR-1


Nankang AR-1 

UPDATE: We have been told that the NHTSA has accepted the updated paperwork from Nankang. Now we wait while another department actually updates the system which will in turn clear the containers for entry into the US. This is an ongoing situation with all incoming containers of Nankang AR-1 and CR-S v2.  This affects ALL dealers in the US.  It is unclear when they will actually clear customs but we finally have reason to be hopeful.

To be clear this has NOTHING to do with the quality or safety of the Nankang AR-1 and CR-S v2. This whole thing has been over a single digit on Nankang’s paperwork on file with the NHTSA.  

We are extremely frustrated by this and all we can do is wait. Thank you for understanding.

We have sufficient inventory in many sizes of Nankang AR-1, CR-S v2, and CR-S v1. We are doing our best to update our inventory on the website on a daily basis.

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.
