| 中文摘要: |
| 分析港口轮胎花纹沟底裂原因，并提出解决方案。通过增大倒圆半径优化花纹和花纹沟底设计及增大天然橡胶用量、采用超耐磨炭黑N134和平衡硫化体系优化胎面胶配方，明显改善了港口轮胎花纹沟底裂问题，进一步提高了轮胎质量，延长了轮胎使用寿命。 |
| 英文摘要: |
| The causes of the crack of tread groove bottom of port tire was analyzed，and the solution was put forward.By increasing the blending radius to optimize the design of tread pattern and groove bottom，and increasing the amount of natural rubber，adopting super wear-resistant carbon black N134 and balanced curing system to optimize the tread compound formula，the problem of crack of tread groove bottom of port tire was improved significantly，so the tire quality was further improved，and the tire service life was prolonged. |
