Through the present invention, indoor test results can strongly correlate with tire performance test results performed in the outside. A tire bench testing apparatus prepared by the present invention performs an indoor tire performance test, and comprises: a rotary drum (2) which operates a tire (T) by touching; a supporting shaft (3) which maintains the tire (T) mounted in a rim (J) in a cantilever type to be able to rotate; and an operating unit which rotates and operates the drum (2) or the supporting shaft (3). The drum (2) has an inner circumference (2G) having a simulated road (7) where the tire (T) drives. The inner circumference (2G) has a smooth circular arc shaped surface (2M) which is convex outwardly from a drum radius direction for a cross section including a drum rotary shaft center (2c). |
