PROBLEM TO BE SOLVED: To provide a disc-shaped rubber test piece for a rubber testing machine capable of faithfully reproducing the peripheral shearing force within the earthing surface produced in a tire under an actual use environment. SOLUTION: The disc-shaped rubber test piece for the rubber testing machine is characterized in that the direction in the tumbling direction of the peripheral shearing force within the earthing surface, which is produced in the disc-shaped rubber test piece when the disc-shaped rubber test piece is earthed on the dummy road surface while tumbled to be freely tumbled, transfers in a negative direction from a positive direction until an earthing completion point from the earthing start point to a dummy road surface.
