| Abstract: | The application of 2＋7×0.30ST steel cord instead of 3×0.20＋6×0.35HT steel cord in belts of 12R22.5 18PR tubeless radial tire was studied.The results showed that the inflated peripheral dimension，durability，high-speed performance and rolling resistance of the finished tire using 2＋7×0.30ST steel cord met the requirements of national or enterprise standards.The single tire weight and production cost were reduced，which could better meet the market demand. |
