The present invention aims to solve the problem of providing a technology which can evaluate the wet road surface performance of a tire at a level equivalent to the evaluation using an actual vehicle through the Finite Elements Method (FEM) computational analysis technology. A method for measuring a wet road surface braking performance of a tire for a vehicle comprises the steps of: (s100) measuring a coefficient of friction (μ) of a rubber specimen using a rubber coefficient of friction measuring instrument comprising a frame (100) on which a test road surface (110) is installed, and a linear motion bearing (300) installed on an upper part of the frame (100) which linearly moves a rubber specimen (200) rubbing against the test road surface (110); and (s200) calculating a braking distance (slip) in accordance with the following equation (1).

    본 발명은 타이어의 젖은노면 제동성능(Wet grip 성능) 평가방법에 관한 것으로서, 더욱 상세하게는, FEM(Finite Elements Method) 전산해석 기술을 이용한 타이어의 젖은노면 제동성능 평가방법에 관한 것이다. 이에, 본 발명은 차량용 타이어의 젖은 노면 제동성능 측정방법에 있어서, 시험노면(110)이 설치되는 프레임(100)과, 상기 프레임(100)의 상부에 설치되며 상기 시험노면(110)에 마찰되는 고무시편(200)을 직선운동시키는 직선운동베어링(300)을 포함하여 구성되는 고무 마찰계수 측정기를 이용하여 고무시편의 마찰계수(μ)를 측정하는 단계(s100); 및 하기의 식1에 의해 제동거리(slip)를 산출하는 단계(s200);를 포함하는 차량용 타이어의 젖은 노면 제동성능 측정방법을 제공하는 것을 특징으로 한다.
