The present invention relates to a method and a device for measuring a tire tread shape, which is for measuring the distribution of tire ground pressure, and measuring the center of ground pressure from the tire tread shape. Accordingly, the center of the ground pressure can be measured in the tire so that a separation distance between the center of a ground image and the center of the ground pressure can be used as a tire performance indicator. The method for measuring a tire tread shape may include a step of applying a load to a mounted tire, and a step of measuring pressure and contact geometry within the tire contact surface.

    본 발명은 타이어의 접지 형상 측정 방법 및 장치에 있어서, 타이어 접지 압력의 분포도를 측정하기 위한 것으로서, 타이어의 접지형상으로부터 접지 압력 중심을 측정하기 위한 것이다. 이를 통해 타이어에서 접지 압력의 중심을 측정할 수 있으므로 접지 이미지의 중심과 접지 압력의 중심의 이격거리를 타이어의 성능 지표로 삼을 수 있다.
