A method of timing a remarkable angular position (θR) of at least one sensor (12) carried by a tire (10) rotating relative to an external frame of reference. The following steps are performed: forming, from an output signal from the sensor (12), a reference signal suitable for presenting a remarkable extremum during one revolution of the tire (10); determining the time of an origin angular position (θ0) of the sensor as being the time of the remarkable extremum of the reference signal; and determining the time of the remarkable angular position (θR) relative to the time of the origin angular position.
