PROBLEM TO BE SOLVED: To provide a tire testing machine capable of measuring dynamic characteristics of a plurality of tires at once, and capable of enhancing precision of a result of the dynamic characteristic of the measured tire. SOLUTION: This tire testing machine 1-1 for measuring the dynamic characteristic of the tire is provided with a driving roller 2 rotated by a motor 22, driven rollers 3, 4 rotated together with the rotation of the driving roller 2, an endless belt 5 laid woundly over on the driving roller 2 and the driven rollers 3, 4, and a tire contact means (the first tire support device 6, the second tire support device 7, a support block 8) for supporting rotatably the plurality of tires T1, T2, and for bringing the plurality of tires T1, T2 into contact respectively with both faces (outer circumferential face 51, inner circumferential face 52) of the endless belt 5. A load is supported mutually by the paired tires T1, T2 contacting with the both faces of the endless belt 5. COPYRIGHT: (C)2007,JPO&INPIT
