| 中文摘要: |
| 介绍高负荷195/70R15LT 12PR 109/105R全钢子午线轮胎的开发。结构设计采用现有模具轮廓尺寸。施工设计：胎面采用四复合（胎面胶、基部胶、小胎侧胶和导电胶）挤出方式，胎体采用1＋5×0.18UT钢丝帘线替代原聚酯帘线，胎圈部位增加补强层，三角胶高度为50 mm。轮胎的充气外缘尺寸、强度性能、高速性能和耐久性能均满足国家标准要求，高负荷耐久性能超过原同规格半钢子午线轮胎的1倍以上，可有效提高轮胎的乘载能力。 |
| 英文摘要: |
| The development of high-load 195/70R15LT 12PR 109/105R all-steel radial tire was introduced.The structure design adopted the existing mold profile dimensions.Construction design：the tread employed four-component（tread compound，base compound，small sidewall compound and conductive compound） extrusion，the carcass using 1＋5×0.18UT steel cord to replace the original polyester cord，reinforcement layer for the bead area，and the height of apex was 50 mm.The inflated peripheral dimensions，strength，high-speed performance and durability of the tire all met national standards，and the high-load durability exceeded that of the original same size steel-belted radial tire by more than 1 time，effectively enhancing the load-carrying capacity of the tire. |
