Abstract	Tire tread compounds usually consist of polymer blends. In this paper the friction for immiscible SBR blends which consist of two different SBRs having different glass transition temperatures of -51 °C and -6 °C are investigated. The effects of the blend ratio of these two SBRs and the added fillers such as carbon black and silica on the friction are also investigated. The friction forces are measured when rubber specimens are rubbed against dry or wet metal gauze. The friction force-sliding speed curves for the SBR blends are related to their storage modulus E’, loss tangent tan δ, contact area A and shear strength s. The adhesion component of the friction for each SPR blend shows a peak at the sliding speed range examined. As the blend ratio of the SBR having higher Tg of -6 °C is raised, the peak value is lowered and the peak shifts to lower sliding speed. The adhesion component of the friction for silica-filled SBR blends is higher than that of carbon black-filled SBR blends. These trends are also shown when rubber specimens are rubbed against the wet metal gauze. On the other hand, the hysteresis component of friction is raised when the blend ratio of the SBRs having higher Tg is increased.
