A wheel rim having an axis of rotation, the rim including a first element in the form of a section of a solid of revolution about the axis, made in a single unitary piece from composite material and including a first end and a second end distinct from one another. The first element is made by pultrusion and constitutes, between the first end and the second end, a section of a solid of revolution having an angular arc greater than 350°, the composite material of the first element includes fibers embedded in a thermosetting matrix, the fibers constituting at least 50% of the weight of the first element.
