PROBLEM TO BE SOLVED: To provide a method for estimating a performance value by the other testing machine with high accuracy from the performance value of the tire obtained by one testing machine.SOLUTION: An estimation method of a performance value of a tire by the other testing machine according to the present invention includes: a measuring force acquisition step of acquiring a measuring force generated in a testing tire by one testing machine; an estimated measuring force acquisition step of converting the measuring force acquired by the measuring force acquisition step into an estimated measuring force generated in the testing tire by the other testing machine; and a performance value acquisition step of acquiring the testing tire by which the performance value of the testing tire is acquired by dividing this estimated measuring force by a testing load. A correlation between the measuring force by this one testing machine and the measuring force by the other testing machine is acquired from the measuring forces of a plurality of master tires acquired by one testing machine and the measuring forces of the plurality of master tires acquired by the other testing machine.SELECTED DRAWING: Figure 1
【課題】一の試験機で得られたタイヤの性能値から、他の試験機での性能値を高精度に推定する方法の提供。【解決手段】本発明に係る、他の試験機でのタイヤの性能値の推定方法は、一の試験機で試験タイヤに発生する測定力が得られる測定力取得工程と、測定力取得工程で得られる測定力を他の試験機で試験タイヤに発生する推定測定力に換算する推定測定力取得工程と、この推定測定力が試験荷重で除されて試験タイヤの性能値が得られる試験タイヤの性能値取得工程とを備えている。この一の試験機での測定力と他の試験機での測定力との相関関係は、一の試験機で得られた複数のマスタータイヤの測定力と他の試験機で得られた複数のマスタータイヤの測定力とから求められている。【選択図】図1
