A computer-implemented method for detecting air loss in a vehicle tire (3), the method comprising measuring a time series of air temperature values inside the vehicle tire (3); measuring a time series of air pressure values inside the vehicle tire (3); selecting a first group of air temperature values and a second group of air temperature values; selecting, a group of air pressure values; deriving a first air temperature value based at least in part on the first group of air temperature values and deriving a second air temperature value based at least in part on the second group of air temperature values; deriving an air pressure value based at least in part on the group of air pressure values; calculating an estimated air temperature value based at least in part on (i) the derived first or second air temperature value, (ii) the change in temperature between the derived first and second air temperature values, and (ii) a predetermined time constant; calculating an estimated normalised pressure based on the estimated air temperature value and the derived air pressure value; and determining if air loss has occurred based at least in part on monitoring said estimated normalised pressure over time.
