| 中文摘要: |
| 介绍新型RT越野轮胎的花纹设计。RT越野轮胎融合了全地形轮胎（AT轮胎）与泥地轮胎（MT轮胎）的优势，具有排水甩泥性能和抗撕裂越野性能优异、操控性能好、噪声小等优点。RT越野轮胎的花纹整体采用大块状组合设计，两侧的胎肩花纹块采用高强度的MT轮胎块状花纹，内侧花纹块采用高强度且可保证轮胎平稳行进的AT轮胎块状花纹；中间花纹块采用类古代刀币设计；周向采用宽且深的主横纵沟贯通设计，辅助类树枝状纵沟设计；胎肩花纹块采用台阶边缘设计，胎肩边缘采用高低交替断差开放式设计；胎侧采用凹凸咬合设计。RT越野轮胎室内性能满足国家标准要求，实车测试在乘坐舒适性、干湿地操控性及越野性能方面表现良好。 |
| 英文摘要: |
| The pattern design of new RT cross-country tire was introduced.The RT cross-country tire combined the advantages of all-terrain tire（AT tire） and mud tire（MT tire），which had the advantages of excellent drainage and sludging performance and tear-resistance cross-country performance，good handling performance and low noise.The overall pattern of RT cross-country tire was a combination of large blocks，the shoulder pattern on both sides was composed of strong MT tire block pattern，and the inner pattern was composed of strong but smooth AT tire block pattern.The middle pattern was designed like ancient knife coins.In the circumferential direction，a wide and deep main transverse and longitudinal groove was designed，and an auxiliary dendritic longitudinal groove was designed.The tread shoulder pattern block adopted step edge design，and the edge of tire shoulder adopted high and low alternating break difference open design.The concave and convex occlusal design was used on the sidewall of tire.The indoor performance of RT cross-country tire met the requirements of national standards，and the real vehicle test results showed good ride comfort，dry and wet handling and cross-country performance. |
