A method for determining a vehicle wheel's radial acceleration for a tyre pressure monitoring system, having a central electronic unit. The wheels each including a wheel unit attached to a rim or to a valve or the tyre tread's inner face, and including at least one radial acceleration sensor at a distance from the wheel's rotational axis, to measure the wheel's radial acceleration when it is not saturated, and a microprocessor, including: when the radial acceleration sensor is not saturated, measuring the radial acceleration of the wheel using the radial acceleration sensor; determining the wheel's rotation period; deducing, from the radial acceleration and the period, the distance of the wheel unit; storing the distance in the wheel unit's memory; and when the radial acceleration sensor is saturated, determining the wheel's rotation period, and calculating the radial acceleration from the rotation period and the stored distance.
