PURPOSE:To efficiently manufacture the same wheels different in offset values by car kinds with minimum number of dies by press working a light alloy forged disc material or a disc part with press material. CONSTITUTION:A vehicle wheel with a forged disc part 4 or its material of the light alloy formed by forging or spinning, etc., is loaded on a prescribed dies 5. The disc part 4 or the disc part material is pressed by a cylindrical press material 7 to elastic deform to prescribed offset value L2. The vehicle wheel of the same wheel different in the offset value L2 by the car kinds is manufactured by the minimum dies to improve the working efficiency and to reduce the total stock.
