| 中文摘要: |
| 介绍7.00R16LT全钢轻型载重子午线轮胎的轻量化施工设计。带束层由3层结构调整为2层结构，钢丝圈由3-6-3调整为4-6-4，内衬层厚度整体减小0.2 mm，隔离胶宽度减小60 mm，三复合总宽度从205 mm减小至200 mm。结果表明，轻量化后的成品轮胎充气外缘尺寸、强度性能、耐久性能、高速性能、胎圈耐久性能均符合设计、国家标准和企业标准要求，成本明显降低。 |
| 英文摘要: |
| The lightweight construction design of 7.00R16LT all-steel light truck and bus radial tire was introduced.The belt structure was adjusted from three-layers to two-layers structure and the bead was adjusted from 3-6-3 to 4-6-4.The thickness of inner liner was reduced by 0.2 mm.The width of insulating compound was reduced by 60 mm and the width of triplex side wall was reduced from 205 mm to 200 mm.The results showed that the inflated peripheral dimension，strength，endurance performance，high-speed performance and bead endurance of the finished lightweight tire all met the requirements of design and national standards，the cost was reducted significantly. |
