For best performance, Nankang recommends a camber range of -1.0 to -3.0 degrees. Recommended hot pressure settings are 23–27.5psi for vehicles under 800kg, 24–32psi for vehicles between 800–1000kg, 27.5–37psi for vehicles between 1000–1400kg, and 34–42psi for vehicles over 1400kg. For cold pressure setup, use the highest figure relevant to the vehicle weight and work down after warm laps. For example, a 950kg vehicle should start from 32psi, while a 1250kg vehicle should start from 37psi. For road use, tyre pressures should follow the vehicle manufacturer’s guidelines. Tyre pressure guidance is provided as a general starting point only. Recommended pressures can vary depending on tyre size, vehicle weight, wheel setup, alignment, suspension, driving style, circuit conditions and ambient temperature.
