| Abstract: | The truck and bus radial tire for short and middle distance was improved by taking 12.00R20 18PR tire as an example. It was found that the durability of the bead was greatly improved by reducing the turn-up height of carcass cord,increasing the width of steel chafer,adding 2 layers of nylon chafers on each side of steel chafer,and optimizing the formula of upper and lower bead filler. |
