Special Pricing on CR-S v1 Clearance pricing as shown below Competition Tire 200 treadwear *** Nankang CR-S Specs *** Have your competition tires heat cycled today and be race ready! Free Shipping 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% ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ PTSBUY3GET1 – Buy 3 Nankang CR-S v1 sizes and Get 1 Free (The tires on promotional pricing are 2021 and 2022 date codes due to overstock from the factory.
