An apparatus for fitting proper sizes of balance weights to the inner and outer rims of a wheel at proper positions. The apparatus includes a wheel balance measuring station and a balance weight fitting station arranged side by side. In the balance weight measuring station, the wheel is measured to detect unbalance of the wheel so as to determine sizes of balance weights to be fitted to the rims and positions at which the balance weights are fitted. According to the determination, weight size signals and position signals are provided and sent to the balance weight fitting station. In the balance weight fitting station, upper and lower balance weight handling devices electromagnetically pick up the determined sizes of balance weights among various sizes of balance weights supplied by upper and lower balance weight supplying devices according to the weight size signals; and upper and lower balance weight fitting devices receive the electromagnetically picked up balance weights and bring them above and below the outer and inner rims of the wheel, respectively, according to the position signals. The upper balance weight fitting device descends to fit the determined size of balance weight to the outer rim edge of the wheel at the determined position. On the other hand, the lower balance weight fitting device turns upside down and then ascends to fit the determined size of balance weight to the inner rim edge of the wheel, thereby finishing the fitting of the balance weights to the wheel.
