PURPOSE: A device for measuring the dynamic ground contact pressure and a grounded shape of a tire is provided to effectively measure the distribution of the ground contact pressure of the tire as the compressed extent of tread is subdivided and indicated with colors. CONSTITUTION: A device for measuring the dynamic ground contact pressure and a grounded shape of a tire comprises a ground plate(3), a column(5), a load support frame(6), a 3-component load cell(7), a screw jack(8), and a rotary joint(9). The surface of a tempered glass ground plate installed on a test road(2) is emboss-processed, thereby being formed into a lattice shape. The column is arranged inside the basement(1) in order to obtain a gradient of the road while possess-supporting the ground plate. The load support frame possess-supports the column. The 3-component load cell is installed in the upper part of the column, thereby being in contact with the lower end surface of the ground plate. The screw jack and the rotary joint move the column upwardly and downwardly. A block rubber sheet(11) with a high elongation ratio is mounted in the upper end surface of the ground plate while a white medium liquid layer(10) is interposed between the medium liquid layer and the rubber sheet.
