The invention provides a making method for a forward and reverse rim. The method includes the following steps that a board is extruded at high intensity to form a profile with a first protruding part and a second protruding part; the profile is rolled into a hollow cylindrical barrel, and the first protruding part and the second protruding part on the profile form two sets of assembling steps or assembling ribs in the barrel; a barrel seam formed when the profile is rolled is welded through friction stir welding equipment; the two ends of the barrel are turned to form felloes which extend outwards and are turned inwards; the outer side of the first protruding part is subjected to rotary extrusion to form a third protruding part; the barrel is subjected to heat treatment; the barrel is subjected to precision machining to form a bead seat on the barrel, and the forward and reverse rim is obtained. According to the making method for the forward and reverse rim, the rim adapts to a forward installation mode and a reverse installation mode; besides, the machining process is simple, and the rim making time is shortened. No casting or forging die is needed in the making method for the forward and reverse rim.
