Abstract:
To provide a tire testing device which easily resists the positional deviation in the rotation direction to a hub of a wheel and prevents the breakage of fastening means that fixes the wheel and the hub.SOLUTION: A tire testing device comprises: a tire support part which has a travel base, a wheel 16 and a hub 13, and supports an evaluation object tire X in a rotatable manner via the wheel 16 and the hub 13; and a plurality of fastening members 17, 18 which fastens the wheel 16 to the hub 13. The wheel 16 has a wheel side uneven part 30a which becomes uneven in the tire axial direction at one or a plurality of positions in the tire circumferential direction on an attachment object surface 16c attached to the hub 13. The hub 13 has a hub side uneven part 30b which becomes uneven in the tire axial direction at one or a plurality of positions in the tire circumferential direction on an attachment object surface 13c attached with the wheel 16. The wheel side uneven part 30a and the hub side uneven part 30b constitute a contact uneven pair 30 which is complementary so as to be in contact with each other in the tire axial direction.SELECTED DRAWING: Figure 5
