<p>The present invention provides a tire bench testing apparatus by which a test result having a higher correlation with a performance test result of a tire which is carried out in the field can be obtained in a room. The tire bench testing apparatus (1) carrying out the performance test of the tire in the room comprises a drum (2) which enables the tire (T) to be contacted and drive and can rotate; a supporting shaft (3) which keeps the tire (T) assembled in a rim (J) to be rotatable in a cantilever manner; a driving unit for rotating and driving the drum (2) or the supporting shaft (3). The drum (2) possesses an inner circumferential surface (2G), and the inner circumferential surface (2G) possesses a simulation road (7) on which the tire (T) can drive, and a smooth arc-shaped surface (2M) protruded towards a radial outside of the drum in a cross-section having the rotation axis (2c) of the drum.</p> |
