| 中文摘要: |
| 以现有燃油汽车用145/70R12 69T半钢子午线轮胎为基础进行某微型新能源汽车车型配套轮胎的设计与优化。通过两半模模具中间部位宽度减小6 mm，减小花纹沟深度，相应的带束层等半部件宽度和质量减小，可实现轮胎轻量化、降低滚动阻力和噪声，同时保证磨耗里程、外缘尺寸、强度性能、脱圈阻力、高速性能和耐久性能满足相关标准要求。 |
| 英文摘要: |
| The design and optimization of the matching tire of a minitype new energy vehicle were carried out based on the 145/70R1269T steel-belted radial tire for the fuel vehicles.By reducing the width of the middle part of the two half mold by 6 mm and reducing the depth of the pattern groove，the width and weight of the belt and other half components could be reduced，which could achieve lightweight of the tire，reduce rolling resistance and noise，and ensure that the wear mileage，peripheral dimension，strength performance，bead unseating resistance，high speed performance and durability meet the requirements of corresponding standards. |
