Abstract: The present disclosure relates to a method of inflating a tire and a central tire inflation system. The system has the tire connected to a pressure port for applying an air pressure via a pneumatic line. An ambient air temperature and a target pressure for the tire is received and a tire inflation rate based on the ambient air temperature and the target pressure is calculated. An estimated pressure of the tire based on tire inflation rate is estimated and the tire is inflated at the calculated tire inflation rate. A pressure of the tire is measured and a correction factor based on a ratio between the measured pressure and the estimated pressure is calculated. The tire inflation rate using the correction factor is corrected and the tire is inflated at the corrected tire inflation rate until the target pressure is reached.
