A method of making a rim of sheet metal for a vehicle wheel, in which: a rectangular geometric shape is cut out of a blank of sheet metal; the blank is bent to obtain a cylindrical hoop; the two free edges of the hoop are welded together; at least one cylindrical flow spinning operation is performed to obtain a profile of given thickness of the hoop, zones of constant thickness being adjacent to zones of variable thickness; a cut is made perpendicular to the axis of the hoop out of at least one lateral edge of the hoop; the hoop is profiled to obtain the rim; and the size of the said rim is set.
