摘　　要：对11R22.5无内胎载重子午线轮胎结构进行优化设计。通过采取减小胎面厚度,同时保证花纹沟底部橡胶厚度,减小内衬层厚度,在保证带束层钢丝端点水平的前提下减小胎肩垫胶厚度以及调整三角胶尺寸等措施,在不降低轮胎安全倍数的前提下,可使轮胎质量减小,胎肩部位散热能力改善,耐久性能提高,使用寿命延长。In this study, the structure of 11R22.5 tubeless truck and bus radial tire was optimized. In the optimized structure, the tread thickness was reduced while the thickness in the groove part was maintained, the innerliner thickness was also reduced, the thickness of the cushion rubber in tire shoulder was reduced under the condition that the steel wire endpoints of the belt layer were kept at the same level, and the apex size was adjusted. After the modification, without lowering the safety factor of the finished tire, the tire weight was reduced, the heat dispersion of the tire shoulder was improved, the endurance performance increased, and the service life prolonged.
