To provide an evaluation method of durability performance of a tire, capable of rapidly and accurately evaluating durability performance of a heavy load duty tire incorporating an RFID tag.SOLUTION: An evaluation method for evaluating durability performance of a heavy load duty tire having a tread and incorporating an RFID tag includes reclaiming the tread worn by travel when a period from start of use to reach of a use limit is set as a period of service so as to define a second period of service after reclamation in addition to a first period of service before reclamation. The evaluation method includes a processing step S2 and a travel step S4. In the processing step S2, heat deterioration processing is performed for a test tire T so as to generate on the test tire T, a change of a state corresponding to a change of a state of the tire in the first period of service.SELECTED DRAWING: Figure 9

    【課題】RFIDタグを内蔵した重荷重用タイヤの耐久性能を迅速かつ正確に評価できる、タイヤ耐久性能の評価方法の提供。【解決手段】この評価方法は、トレッドを有し、使用を開始してから使用限界に到達するまでの期間を使用期間としたとき、走行により摩耗した前記トレッドを更生することで、更生前の第一使用期間に加え、更生後の第二使用期間が設定される、RFIDタグを内蔵した重荷重用タイヤの耐久性能を評価するための方法である。この評価方法は、処理工程S2と、走行工程S4とを含む。処理工程S2において、第一使用期間におけるタイヤの状態変化に相当する状態変化がテストタイヤTに生じるように、熱劣化処理がテストタイヤTに対して行われる。【選択図】図9
