中文摘要:
      介绍8.25R16LT 16PR全钢轻型载重子午线轮胎的设计。结构设计：外直径　861 mm，断面宽　235 mm，行驶面宽度　205 mm，行驶面弧度高　6 mm，胎圈着合直径　403 mm，胎圈着合宽度　176 mm，断面水平轴位置（H1/H2）　1.10，胎面花纹采用等节距设计，花纹深度　18 mm，花纹饱和度　68.5%，花纹周节数　34。施工设计：胎面采用热冷喂料双复合挤出，采用3层带束层＋2层0°带束层结构，1#—3#带束层采用3×0.20＋6×0.35HT钢丝帘线，0°带束层采用3×7×0.20HE钢丝帘线，胎体采用0.22＋6＋12×0.20HT钢丝帘线，采用三鼓式一次法成型机成型，双模B型热板硫化机硫化。成品轮胎性能试验结果表明，轮胎的外缘尺寸、强度性能、耐久性能和高速性能均符合设计和国家标准要求。
英文摘要:
      The design on 8.25R16LT 16PR all-steel light truck radial tire was described.In structure design，the following parameters were taken：overall diameter?861 mm，cross-sectional width?235 mm，width of running surface　205 mm，arc height of running surface　6 mm，bead diameter at rim seat?403 mm，bead width at rim seat?176 mm，maximum width position of cross–section（H1/H2）?1.10，equal pitch design for tread pattern，pattern depth?18 mm，block/total ratio?68.5%，and number of pattern pitches?34.In construction design，the following processes were taken：co-extruded tread with both hot and cold feeding，3 layers of regular belts plus two layers of 0° belts for the belt ply，3×0.20＋6×0.35HT steel cord for 1#—3# belts，3×7×0.20HE steel cord for 0° belts，0.22＋6＋12×0.20HT steel cord for carcass，using three-drum one stage building machine to build tire，and type B double mold hot plate curing press to cure tires.It was confirmed by the finished tire test that，the inflated peripheral dimension，strength，endurance and high speed performances reached the requirements of the design and national standards.
