Application of 2+7×0.30ST Steel Cord in 12R22.5 18PR Tubeless Radial Tire
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.
