A device for measuring a ground contact surface of a tire with a camber angle is provided to get real ground contact data which is similar to ground contact data of the tire of a vehicle and to cut down costs required to measure a ground contact surface. A device for measuring a ground contact surface of a tire with a camber angle comprises a stationary support(11), a tire supporting shaft(12), a load plate(14), and a load unit(13). The fixing support is used to separate and support a thread surface from a ground surface at both sides of a test tire(10) at a regular degree. The tire supporting shaft is fixed to the tire and formed with both ends combined with the fixing support rotatably. The load plate is formed with a measuring paper(15) positioned at an upper surface and used as the ground contact surface of the tire. The load unit is used to give vertical load to the tire through the load plate. The load plate is combined with the load unit rotatably and formed with an angle controller controlling a rotational angle of the load plate according to the camber angle of the tire. A center bracket(16) formed at a center portion of a lower end for the load plate is hinge-fixed to an upper end portion of the load unit.
