Abstract: In the tire industry, there are competitions in both of price and tire quality. Most of the produced tire components are sidewall. To reduce the production cost, the aim of this research is the use of silica (Si) to replace the carbon black (CB) partially and produce the sidewall compound since Si was cheaper than CB. At the constant filler loading of 51 parts per hundred of rubber (phr), the sidewall compound mixed with Si- filler at 4.90 percent, 9.80 percent, and 14.71 percent without the assistance of any coupling agents. The properties of the sidewall in terms of Mooney viscosity, cure characteristics, tensile properties, crosslink density, thermal aging properties, rebound, and hardness of the vulcanizates were investigated. The results showed that Mooney viscosity of the sidewall compound mixed with small amount of Si was not significantly changed. However, the increased amount of Si-filler to 14.71 percent increased the scorch time, cure time and elongation at break of the vulcanizates. Moreover, the addition of Si decreased the hardness, rebound and tensile strength of the vulcanizates compared to the one which contained only CB. This might be attributed to crosslink density that declined by the interaction between silanol groups on the Si-filler surface with accelerators.
