A method for designing a tire profile with bent of a belt layer is provided to design a tire satisfying a desired performance by previously considering change of a tread shape/pressure of each tread block as well as the change of entire tread shape/pressure when the tire profile is designed. A user sets up a size and detail dimension of a tire(S1), and the user sets the number and a position of grooves of a tread(S2). The user selects a tire profile(S3). An FEA(Finite Element Analysis) and performance estimation are performed(S4). Bent of a belt layer is induced again in a stage for selecting the tire profile including the bent of the belt layer, and the induced bent is fed back to an FEA and performance estimation stage when the desired tread shape/pressure distribution is not obtained in the FEA and performance estimation stage.
