A method for making the composite material wheel rim comprises the steps of: configuring a plurality of inner lining chunks individually to the desired position where the spokes are to be mounted so as to allow the inner lining chunks to be integrated with an inner annular portion of the wheel rim, next, integrating the formed inner annular portion with an outer annular portion of the wheel rim to form a semi-finished wheel rim, and then, creating the requested threaded holes for connecting the spokes in the inner lining chunks of the inner surface of the semi-finished wheel rim subject to the requested amount and angles of the spokes. By the prevent method, the semi-finished wheel rim allows to be drilled threaded holes subject to needs to fit different types of wheel hub units so as to increase the yield rate and reduce the inventory of the wheel rims.
