245/40ZR17 TYRE Nankang CRS

Product introduction

The Nankang CRS / CR-S tyre in size 245/40/17 is a road-approved semi-slick designed for sports vehicles, performance-focused builds and track outings such as trackdays, historic hill climbs or intensive recreational use. Developed to deliver high levels of grip and precise feedback, it is aimed at drivers seeking a high-performance tyre capable of withstanding heavy demands while remaining suitable for public roads.

Role of the part

The tyre provides the direct connection between the vehicle and the road. It transfers engine power, braking forces and cornering loads to the ground. On a sports vehicle, tyre choice is crucial for traction, steering precision, high-speed stability and consistent performance during dynamic driving.

The Nankang CRS / CR-S uses a competition-style tread with an outer design inspired by rally tyres, promoting lateral grip and handling under cornering loads. The inner grooves help disperse water, while the intermediate micro-grooves help dissipate heat during sustained use.

Symptoms or consequences of a worn or defective tyre

• Loss of grip under acceleration, braking or cornering
• Longer braking distances, particularly on wet surfaces
• Reduced steering precision and feedback through the steering wheel
• Uneven wear that may cause vibrations or unstable handling
• Increased risk of aquaplaning if the grooves no longer disperse water effectively
• Reduced performance during sports driving or on track

Benefits of replacement

• Improved grip on dry roads and during dynamic driving
• Better stability under cornering loads thanks to a stiff sidewall
• More precise chassis feedback and more direct steering
• Optimised water dispersion thanks to wide circumferential grooves
• Better temperature management under heavy demands
• Road-approved semi-slick tyre suitable for sports vehicles used on roads and recreational circuits
