PROBLEM TO BE SOLVED: To provide a simulation method for locating a position where influence degree on vibration performance or rolling resistance performance of a tire is high, and a manufacturing method.SOLUTION: A simulation method of a tire includes: a step S1 of setting a tire model in which a tire is modeled by a finite number of element F(i); a first calculation step S4 of causing a computer to calculate first distortion energy loss Ea of the tire model; a second calculation step S5 of causing the computer to calculate second distortion energy loss Eb of the tire model; and a step S7 of causing the computer to calculate a deformation and vibration parameter Ea/Eb obtained by dividing the first distortion energy loss Ea by the second distortion energy loss Eb or a deformation and vibration parameter Eb/Ea obtained by dividing the second distortion energy loss Eb by the first distortion energy loss Ea, for each element F(i).SELECTED DRAWING: Figure 3 【課題】タイヤの振動性能又は転がり抵抗性能への影響度が高い位置を特定するシミュレーション方法及び製造方法を提供する。【解決手段】コンピュータに、タイヤを、有限個の要素Ｆ（ｉ）でモデル化したタイヤモデルを設定する工程Ｓ１、コンピュータが、タイヤモデルの第１歪エネルギーロスＥａを計算する第１計算工程Ｓ４、タイヤモデルの第２歪エネルギーロスＥｂを計算する第２計算工程Ｓ５、及び各要素Ｆ（ｉ）について、第１歪エネルギーロスＥａを第２歪エネルギーロスＥｂで除した振動・変形パラメータＥａ／Ｅｂ、又は第２歪エネルギーロスＥｂを第１歪エネルギーロスＥａで除した変形・振動パラメータＥｂ／Ｅａを計算する工程Ｓ７を含む。【選択図】図３
