315/30ZR21 TYRE Nankang CRS

Product introduction

The Nankang CRS / CR-S tyre in size 315/30/21 is a road-legal semi-slick designed for powerful sports cars, performance builds and track day outings. Developed to deliver high levels of grip and precision, it combines a motorsport-inspired tread pattern with a construction suited to road use.

Role of the component

The tyre provides the direct link between the vehicle and the road. On a sports or modified car, it plays an essential role in traction, braking, high-speed stability and cornering precision. The Nankang CR-S is designed to maximise the contact patch, improve grip under cornering loads and provide more direct driving feedback.

Its tread incorporates two wide circumferential grooves on the inner section to aid water evacuation. The outer section, designed along similar lines to a competition tyre profile, improves lateral grip and manoeuvrability under high cornering loads.

Symptoms or consequences of a worn or defective tyre

• Loss of grip under acceleration, braking or cornering loads
• Longer braking distances, especially on wet roads
• Lack of steering precision and less controlled sidewall feedback
• Uneven wear that may cause vibration or unstable handling
• Increased risk of aquaplaning if the grooves no longer evacuate water effectively
• Reduced performance during sports driving or circuit use

Benefits of replacement

• High grip on dry roads and during sports driving
• Improved cornering stability thanks to a stiff, precise sidewall
• Effective water evacuation through the wide inner grooves
• Optimised heat management through the micro-grooves in the intermediate tread area
• More direct steering feedback and sportier handling
• Road-legal tyre suitable for road journeys and track days
• An excellent balance for high-performance vehicles used at track days, historic hillclimbs or for spirited driving
