| 中文摘要: |
| 研究以2＋7×0.30ST钢丝帘线替代3×0.20＋6×0.35HT钢丝帘线在12R22.5 18PR无内胎子午线轮胎带束层中的应用。结果表明：使用2＋7×0.30ST钢丝帘线的成品轮胎外缘尺寸、耐久性能、高速性能和滚动阻力满足国家或企业标准要求；单胎质量减小，生产成本降低，可以更好地满足市场需求。 |
| 英文摘要: |
| 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. |
