235/40ZR17 TYRE Nankang CRS

Product introduction

The Nankang CRS / CR-S tyre in size 235/40/17 is a road-approved semi-slick designed for drivers seeking high levels of grip during sports road driving, trackdays, historic hill climbs or recreational circuit use. Developed to deliver behaviour close to a competition tyre while remaining suitable for public roads, it combines driving precision, sidewall stiffness and strong traction.

Role of the part

The tyre provides direct contact between the vehicle and the road. It transfers acceleration, braking and cornering forces. On a sports vehicle, a semi-slick tyre such as the Nankang CR-S allows more effective use of the chassis, suspension and braking thanks to an optimised contact patch and a performance-focused compound.

Its specific tread incorporates two wide circumferential grooves on the inner section, combined with a carefully designed groove sidewall angle and a rounded groove base. This design promotes water dispersion and improves wet-road behaviour compared with a strongly track-focused tyre.

Symptoms or consequences of a worn or defective part

• Loss of grip under acceleration, braking or cornering loads.
• Longer braking distances, particularly on wet surfaces.
• Less precise cornering behaviour and a feeling of vagueness in the running gear.
• Uneven wear that may cause vibrations, rolling noise or loss of stability.
• Increased risk of aquaplaning if the tread depth is insufficient.
• Reduced performance during intensive use on circuits or sports road driving.

Benefits of replacement

• Restores high levels of grip for safer and more effective sports driving.
• Improves steering precision thanks to a stiff and responsive sidewall.
• Optimises traction and stability under heavy demands.
• Promotes heat dissipation thanks to the micro-grooves in the intermediate tread.
• Provides excellent chassis feedback and direct response under cornering loads.
• Allows versatile sports road and recreational circuit use thanks to its road approval.
