In this paper, the pre-slip behaviour was investigated using three different hardness of rubber material and three kinds of rubber materials on smooth flat surface and spheres arraied surface subjected to tangential loading prior to gross slippage.The results of this study showed the following : A change of the vertical displacement is linked with a change of the tangential displacement. The characterization for tangential displacement and tangential force can be indicated three parameters of angular stiffness that means the stiffness at the start of increasing tangential force, peak static friction force and critical displacement at beginning of gross slippage. The angular stiffness on spheres arraied surface is smoller than that on smooth flat surface. The tangential force on spheres arraied surface is generally smaller than that on flat surface in the case of NR and SiR rubber. The critical displacement on spheres arraied surface is larger than that on flat surface in the case of NR and NBR specimens.
