Abstract
A device for measuring a tire ground state includes a traveling surface, a tire drive unit, a measuring sheet, a protection sheet which covers the measuring sheet, and a backward and forward tensile force application mechanism. 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. The backward and forward tensile force application mechanism has a roller which is arranged within the space, and is structured such as to pull at least one end of the protection sheet fixed to the roller in the tire forward traveling direction from the below of the traveling surface by rotating the roller.
