The clay SBR nanocomposites was applied in the inner liner of semi-steel radial tire by replacing an equal amount of BIIR. The experimental testing results showed that, with clay/SBR nanocomposites, the crosslinking density was higher, the physical properties and air tightness were improved, the tire burst defect was reduced significantly, the pressure retention of the finished tire was good, and the speed performance and endurance performance met the requirements of enterprise standards. Compared with BIIR, the cost of clay/SBR nanocomposites was lower. However, the density was higher, so the thickness of inner liner might be reduced accordingly.
