| 中文摘要: |
| 介绍7.00R16低滚动阻力轻型载重子午线轮胎的设计。结构设计：外直径 766 mm，断面宽 202 mm，行驶面宽度 132 mm，胎圈着合直径 156 mm，断面水平轴位置（H1/H2） 1.011 1，采用纵向花纹为主、横向花纹为辅的胎面花纹，花纹深度为10 mm。施工设计：胎面采用翼胶形式，采用3层带束层结构，1#带束层采用4＋3×0.33ST钢丝帘线，2#和3#带束层采用4＋3×0.35ST钢丝帘线，采用两鼓一次法成型机成型、热板式硫化机硫化。成品性能试验结果表明，轮胎的充气外缘尺寸、强度性能、高速性能和耐久性能均达到国家标准和企业标准及相应设计的要求。 |
| 英文摘要: |
| The design on 7.00R16 light truck and bus radial tire with low rolling resistance was introduced.In the structure design，the following parameters were taken：overall diameter 766 mm，cross-section width 202 mm，width of running surface 132 mm，bead diameter at rim seat 156 mm，maximum width position of cross-section（H1/H2） 1.011 1，adopting longitudinal patterns as the main part and transverse patterns as the auxiliary part for tread pattern，and depth of pattern was 10 mm.In the construction design，the following parameters were taken：adopting form of wing compound for tread，adopting three-layer belt，4＋3×0.33ST steel cord for 1#belt，4＋3×0.35ST steel cord for 2# and 3# belts，and using two-drum one-stage building machine to build tires and hot plate press to cure tires.The finished tire performance test results showed that the inflate peripheral dimension，strength，durability and high-speed performance all met the requirements of the national standards，enterprise standards and corresponding designs. |
