Development of 16.00-20 16PR sand tire

介绍16.00-20 16PR沙地轮胎的开发情况。轮胎模型两胎圈间的距离比设计轮辋宽度增大12.5 mm可改善下胎侧屈挠较大的问题;胎冠部位设置4层缓冲帘布层,胎冠帘线角度取49°,可减小机头直径和宽度,优化胎坯断面高宽比;拱形行驶面和浅而窄的花纹沟设计适合沙地使用。成品轮胎性能符合设计要求。

A 16.00-20 16PR sand tire has been developed. The space from bead to bead in tire mold is 12.5 mm greater than the designed rim width to improve the flex in the lower sidewall;fourply breaker is arranged in crown area and 49° ply cord angle is taken in crow area to reduce the drum diameter and width and optimize the aspect ratio of green tire; and the arch running surface of tread and the low and narrow groove in tread patterns are designed to suit the service in sand.
