The invention relates to a method and a device for locating the right or left position of a wheel ( 2 ) of a vehicle ( 3 ). According to the invention, the wheel ( 2 ) is equipped with a magnetic measuring component ( 4 ) comprising a core made of ferromagnetic material on which are arranged, crosswise, two windings designed to present maximum sensitivity axes extending in a plane intersecting the axis of rotation of said wheel, and offset from each other, in this intersecting plane, by a predetermined angle theta, and on movements of the vehicle, a measurement is taken of a signal generated by the variation of a magnetic field at the terminals of each of the windings so as to deliver two periodic signals phase-shifted from each other by (+or -) theta, the direction of rotation of the wheel ( 2 ) is determined from this phase difference and, from this direction of rotation and from the direction of movement of the vehicle ( 3 ), the location of the right or left position of the wheel ( 2 ) is deduced.
