260/660/18 Nankang Slick SL-1 TYRE

Product introduction

The Nankang SL-1 260/660/18 slick tyre is a 100 % competition tyre developed for maximum grip on dry circuits. Nankang's first full slick draws on motorsport experience with its high-performance racing range, notably the renowned AR-1.

Designed for demanding drivers, racing vehicles and intensive track days, the Nankang SL-1 stands out for its completely smooth tread, high-speed stability and consistent grip under heavy loads.

Role of the part

The role of a competition slick tyre is to provide direct contact between vehicle and track by maximising the contact patch. Unlike a road or semi-slick tyre, Nankang SL-1 has no tread grooves, providing optimal dry-track grip.

This design improves corner-exit traction, braking precision, lateral stability and cornering speed. The Nankang SL-1 Slick is therefore for circuit use where outright performance takes priority over versatility.

Symptoms or consequences of a worn or unsuitable tyre

A worn, unsuitable slick or one exposed to too many heat cycles can seriously impair circuit handling. Gradual grip loss can reduce performance, cause instability under cornering loads or increase braking distances.

• Loss of grip during cornering and corner exit
• Less consistent lap times
• Excessive sliding under acceleration or braking
• Uneven wear caused by unsuitable wheel alignment or pressure
• Less effective warm-up
• Increased risk of overheating or premature deterioration

Benefits of replacement

Replacing your tyres with new Nankang SL-1 tyres restores high grip and more precise chassis response. Its slick design offers excellent asphalt contact and improves the vehicle's usable potential in dry conditions.

• Maximum grip on dry tracks
• Better stability in fast corners
• Increased corner-exit traction
• More effective, consistent braking
• Precise, predictable behaviour
• Very good resistance to circuit-use stresses
• Consistent performance lap after lap
