A device for measuring a tire ground state includes a traveling surface, a tire drive unit grounding a tire on the traveling surface and rolls the tire, a measuring sheet mounted to a partial area of the traveling surface for measuring the tire ground state, a protection sheet covering the measuring sheet, and a backward and forward tensile force application mechanism applying a tensile force along a tire forward traveling direction to the protection sheet. A space conducting the protection sheet to a portion below the traveling surface is formed in at least one of a delay side and an advance side of the measuring sheet in the tire forward traveling direction on the traveling surface, and the backward and forward tensile force application mechanism is structured such as to pull at least one end of the protection sheet in the tire forward traveling direction from below the traveling surface.
