Nankang AR-1 – Semi-Slick for Track Days and Motorsport
The Nankang AR-1 is a semi-slick tyre for track days, motorsport, and very sporty vehicles. Its construction is designed for sporty vehicles and uses with high demands on dry precision and temperature stability. It excels in mild to warm temperatures when the tread and compound are within their intended operating range for summer roads. Therefore, when making your selection, not only the correct size matters, but also the actual use between city traffic, country roads, and longer motorway stretches. The balanced concept is aimed at drivers who value predictable everyday characteristics more highly than individual extreme values.
It is aimed at drivers who prioritise dry grip and direct feedback over comfort and extensive wet weather reserves. In cold weather, heavy rain, or standing water, the reserves of a semi-slick tyre are lower than those of a normal road tyre. Below winter temperatures, a summer tyre loses elasticity due to its design; a timely seasonal change therefore remains safety-relevant. Tyre pressure, tread depth, load, and driving style significantly influence real-world behaviour and should be checked regularly. Even a high-quality tyre cannot overcome physical limits in standing water, rapidly changing surfaces, or abrupt manoeuvres.
A motorsport-oriented compound and large tread blocks support grip; road legality and operating limits must be checked for each dimension. Road legality, compound, air pressure, axle geometry, and operating temperature must be observed with particular care. Braking distance, rolling resistance, and rolling noise can differ between two visually similar dimensions and should not be generally derived from the model name. Which EU label values apply depends on the dimension, load and speed index, and the respective special version.

The symbols on the sidewall are not a secret code. Select a symbol and the diagram shows the corresponding measurement.
Tread width
The tread width in millimetres. A wider tyre offers more cornering grip, but also more rolling resistance and usually more noise.
