PURPOSE: A crack evaluation/test apparatus of a tire groove is provided to give data useful for the quality increase of a tire by reliably performing a groove crack performance test while testing on a variety of sizes of tires.;CONSTITUTION: A crack evaluation/test apparatus of a tire groove comprises a drum(2), and a driving part(3). A tire(1) to be tested make contacts with the drum. The drum is connected to the rotary shaft(4) of the driving part and rotates. The crack of the groove is evaluated/tested by the fatigue load applied to the groove of the tire. Slope contact drum parts(6) extended along both radial directions on a center drum part(5) are symmetrically formed at the drum. The slope contact drum parts can be detached/attached to the center drum part conforming to the tire size. The tire is controlled by the controller(7) in load, speed and the rotation number of the drum to be evaluated/tested.;COPYRIGHT KIPO 2010
