240/640/18 TYRE Nankang Slick SL-1

Nankang SL-1 240/640/18 slick tyre, competition performance for circuits

The Nankang SL-1 in size 240/640/18 is a 100 % slick tyre developed for motorsport competition and intensive track use. Designed to offer maximum grip on dry tracks, it is aimed at drivers seeking a high-performance, consistent and durable tyre for sporting driving, advanced track days or races.

Role of the slick tyre

The role of a slick tyre is to optimise the contact patch between vehicle and track. Thanks to its completely smooth tread, the Nankang SL-1 maximises lateral and longitudinal grip in dry conditions. It improves traction, braking stability, steering precision and cornering speed.

Consequences of a worn or unsuitable tyre

A competition tyre that is worn, incorrectly sized or has an ineffective compound can lead to loss of grip, longer braking distances, reduced corner-exit traction and impaired dynamic vehicle handling. On track, this can also cause overheating, uneven wear and loss of consistency over successive laps.

Benefits of replacement

• Maximum dry-track grip thanks to the 100 % slick design
• Improved stability in fast corners and technical sequences
• Optimised traction during hard acceleration
• More precise, consistent braking in track conditions
• Consistent handling across several driving cycles
• Excellent endurance for intensive motorsport use
