The invention relates to the technical field of machining, in particular to a tubeless high-strength steel rim roll forming process design method, which is characterized in that a parting line of a groove bottom is designed in a first roll forming design process, so that the size of the left side of the groove bottom is smaller than that of the right side, and serious thinning of a left side material is avoided; in the first roll forming design, the radius design values of fillets on the two sides of the groove top are 3mm smaller than a target value R, the design value of the groove bottom depth is 5mm larger than the target value H, the design value of the second roll forming design is the same as the design value of the first roll forming, and the design value of the groove bottom depth is the same as the target value H; the design values of the radiuses of the left fillet and the right fillet of the groove top of the third roll forming are 3mm smaller than the target value R, the design value of the depth
