Abstract:
A method of assembling a tire and a wheel, comprising:selecting a predetermined evaluation function based on a physical amount of unbalance which includes a magnitude and a position of an amount of unbalance of a tire and a magnitude and a position of an amount of unbalance of a wheel for assembling with the tire, wherein the predetermined evaluation function allows evaluation of a degree of balance in a particular manner at given phase angles between the tire and the wheel at the time of assembly;predicting evaluation function values at the given phase angles;obtaining a predicted angle for assembling the tire and the wheel which angle gives the optimum value of the predicted evaluation function values; andassembling the tire and the wheel at the predicted angle;wherein the step of selecting a predetermined evaluation function predicts and utilizes, at the time of assembling the wheel and tire at the given phase angles (.theta.), at least one of the amount of unbalance weight to be corrected (n.sub.1) at the front side of the assembled wheel, the amount of unbalance weight to be corrected (n.sub.2) at the reverse side of the assembled wheel, and the amplitude of a radial force variation (RFV) primary component.
