Nankang AR1 road-legal 315/30R18 98Y XL semi-slick tyre

The Nankang AR1 315/30R18 is a high-performance semi-slick tyre designed for sports vehicles, track builds and circuit days. Road-legal, it allows mixed road and trackday use while delivering high grip on dry surfaces once warmed up. Its performance-oriented design makes it a suitable choice for powerful vehicles, sports GTs, Alpine cars, modified Renault Sport cars and cars dedicated to performance driving.

Role of the part

The tyre provides the direct link between the vehicle and the road. It influences traction, braking, steering precision, stability under cornering loads and overall chassis behaviour.

• Longer braking distances
• Less precise steering and less stable handling
• Uneven wear that may cause vibration or imbalance
• Reduced performance after several heat cycles
• Increased risk of loss of control on wet surfaces with an excessively worn tyre

Benefits of replacement
