A method of designing a pneumatic tire, wherein a basic model of a tire representing a cross-sectional shape of the tire including an internal structure, an objective function representing a physical amount for evaluating tire performance, a design variable for determining the cross-sectional shape of the tire, and a constraint for constraining the cross-sectional shape of the tire are determined. A corrected model of the tire with the design variable changed by a unit amount .theta.r.sub.i is determined. The value of the objective function and the value of the constraint in the corrected model are calculated. A sensitivity is calculated for each design variable, and an estimated value of the amount of change of the design variable which maximizes the value of the objective function while taking the constraint is calculated by means of the sensitivities. The above process is repeated until the value of the objective function converges. The configuration of the tire is determined on the basis of the design variable when the value of the objective function has converged to the estimated value.
