Abstract
A method for determining the axle load on a rotating tire or the percentage axle load of a first axle of a moving vehicle. The relationship between the axle load on a test tire and the rolling radius of the test tire under a constant pressure is empirically determined, and optionally the relationship between the pressure of the test tire and the rolling radius of the test tire at a constant axle load is empirically determined. A measurement of the rotational speed of the rotating tire is taken, and optionally a measurement of the pressure of the rotating tire is taken using a pressure sensor. The axle load or percentage axle load is determined from the measurement (or optionally from the measurements) and from the relationship (or optionally from the relationships).
