225/45ZR17 TYRE Nankang CRS

Nankang CRS / CR-S 225/45R17 94W XL semi-slick tyre, not road-approved

The Nankang CRS / CR-S in size 225/45R17 is a semi-slick tyre developed for sports vehicles used on circuits, trackdays, historic hill climbs, recreational driving or performance builds. Designed to deliver high levels of grip and precise steering feedback, it is aimed at drivers seeking a high-performance, responsive and durable tyre for intensive use.

Role of the part

The tyre provides the direct connection between the vehicle and the ground. On a sports car, it plays an essential role in traction, braking, steering precision and stability under cornering loads. The Nankang CRS / CR-S uses a competition-style design with a tread optimised to maximise the contact patch, promote warm-up and ensure excellent cornering grip.

Its two wide circumferential grooves on the inner part of the tread, combined with a greater groove sidewall angle and a rounded groove base, disperse water effectively. This design improves wet-surface behaviour while maintaining the performance expected of a semi-slick.

Symptoms or consequences of a worn or defective tyre

• Loss of grip under acceleration, braking or cornering
• Longer braking distances
• Less precise behaviour during changes in cornering load
• Increased risk of aquaplaning on wet surfaces
• Uneven wear that may cause vibrations or loss of stability
• Reduced steering feedback and driver confidence

Benefits of replacement

• Improved grip on track and during sports driving
• Better driving precision thanks to a stiff sidewall
• More stable behaviour under sustained cornering loads
• Rapid heat dissipation thanks to the micro-grooves in the intermediate tread
• Better wet-surface effectiveness compared with a semi-slick with a very closed tread pattern
• More direct chassis feedback, ideal for sports and modified chassis
