| 中文摘要: |
| 介绍420/85R30拖拉机驱动轮农业子午线轮胎胎面花纹的设计。胎面采用人字形花纹，花纹深度为45 mm，花纹周节数为20，花纹饱和度为23.6%，支撑角度采用变角度设计，前支撑角度为15°～18°，后支撑角度为18°～25°。成品轮胎性能测试结果表明轮胎充气外缘尺寸和物理性能符合设计要求。 |
| 英文摘要: |
| The design on the tread pattern of 420/85R30 agricultural radial tire for tractor drive wheel was introduced.The tread adopted the chevron pattern，the pattern depth was 45 mm，the number of pattern pitches was 20，the block/total ratio was 23.6%，the support angle adopted variable angle design，the front support angle was 15°～18°，and the rear support angle was 18°～25°.The test results of the finished tire showed that the inflated peripheral dimension and physical properties of the finished tire met the requirements of design. |
