To provide a method that can accurately evaluate cornering performance.SOLUTION: A tire performance evaluation method includes: a step of inputting into a computer, a tire model modeling a tire; and a step of inputting into the computer, a road surface model modeling a road surface. Then, the computer executes: a first step of rolling the tire model on the road surface model under a straight-ahead travel condition, and calculating a physical quantity concerning cornering performance of the tire model during rolling; a second step of rolling the tire model on the road surface model under a turning travel condition, and acquiring a physical quantity of the tire model during rolling; and a third step of evaluating a corning performance on the basis of a difference between the physical quantities obtained in the first step and the second step respectively.SELECTED DRAWING: Figure 3

    【課題】コーナリング性能を正確に評価することが可能な方法を提供する。【解決手段】タイヤ性能の評価方法である。この評価方法は、タイヤをモデリングしたタイヤモデルを、コンピュータに入力する工程と、路面をモデリングした路面モデルを、コンピュータに入力する工程とを含み、コンピュータが、タイヤモデルを直進走行条件下で路面モデル上を転動させ、転動中のタイヤモデルのコーナリング性能に関する物理量を計算する第1工程、タイヤモデルを旋回走行条件下で路面モデル上を転動させ、転動中のタイヤモデルの物理量を取得する第2工程、及び、第1工程及び第2工程でそれぞれ得られた物理量の差に基づいて、コーナリング性能を評価する第3工程を実行する。【選択図】図3
