A method for making a carbon fiber wheel rim includes: preparing an outer supporting piece (20); winding a carbon-fiber yarn (30) around the outer supporting piece (20) to form carbon fiber layers and to constitute an engaging seat preform (31); connecting an inner supporting piece (40) to the engaging seat preform (31); connecting a reinforcement piece (50) to the inner supporting piece (40); winding a carbon-fiber yarn (32) around an assembly of the engaging seat preform (31), the inner supporting piece (40) and the reinforcement piece (50) to form carbon fiber layers; fixing the assembly with the carbon fiber layers to form an outer frame preform (33); and cutting the outer frame preform (33) and the engaging seat preform (31) to form a trench (23) and removing the outer supporting piece (20) therefrom.
