The purpose of this experiment was the physical properties of rubber compounds with DPCB and pure carbon black. Si-O peak in the silcia surface was observed at the range of wavenumber from 1,100 to 1,200 in the DPCB by FT-IR analysis. Cure rate of rubber compounds containing DPCB and organic silane coupling agent were (Si69) delayed compared with those containing pure carbon black. 300% modulus and interaction coefficient of DPCB with silane coupling agent were higher than those of pure carbon black and PICO weight loss amount showed constant value. It was found that $0^{\circ}C$ tan$\delta$ of rubber compounds with DPCB was larger than those of pure carbon black at 2.0% silane coupling agent based on 50 phr DPCB and $60^{\circ}C$ tan$\delta$ of rubber compounds with DPCB decreased as increasing the usage coupling agent. Consequently, it is postulated that DPCB is strong candidate material for lowering rolling resistance under constant abrasion resistance.
