275/40ZR18 TYRE Nankang CRS

Nankang CRS / CR-S 275/40R18 103Y XL road-approved tyre

The Nankang CRS / CR-S in size 275/40R18 is a road-approved semi-slick tyre designed for sports vehicles, performance builds and intensive road use, track days, historic hillclimbs or dynamic driving. Developed to offer high levels of grip and precision, it is intended for enthusiasts seeking a high-performance tyre capable of withstanding heavy loads.

Part function

The tyre provides the direct link between the vehicle and the road. It influences traction, braking, stability, steering precision and handling under cornering loads. On a sports vehicle, a semi-slick tyre such as the Nankang CR-S allows effective use of the chassis, engine power and braking while retaining approval for road use.

Its specific tread incorporates two wide circumferential grooves on the inner section, combined with an optimised wall angle and rounded groove base. This design aids water evacuation and improves wet-surface performance. The outer tread features a design inspired by competition tyres to provide excellent lateral grip and good cornering manoeuvrability.
