摘　　要：通过对195/65R15轿车子午线轮胎的骨架材料和施工设计进行优化,以减小轮胎质量,降低轮胎滚动阻力,提高汽车的燃油经济性。结果表明:优化设计后的轮胎质量由8.8kg减为7.3kg;在保证轮胎的充气外缘尺寸、成品性能以及室外装车性能满足要求的情况下,优化后轮胎的湿地抓着性能基本保持不变,滚动阻力系数由10.08降到8.89,降幅达11.8%。The weight of 195/65R15 passenger car radial tire was reduced by optimizing the design of skeleton material and construction, the tire rolling resistance decreased and the fuel economy was improved. After optimization the tire weight decreased from 8. 8 kg to 7. 3 kg. Under the inflated peripheral dimension, tire properties and outdoor performance met the requirements in corresponding standards, the wet grip performance of optimized tire remained unchanged and its rolling resistance ratio decreased by 11.8% ,from 10.08 to 8.89.
