Major difference in Structure between Truck bus radial and cross-ply tire 全钢子午胎和斜交胎在结构方面的主要差别
In the process of tire Building,在轮胎成型过程中 1. Butt splice of carcass ply be recommended for carcass quality
为了保证胎体的质量，建议进行对缝结合
2. The amount of overlap be minimized for Belt splice (max. 1 cords) 带束层结合过程中钢丝搭接的数量尽量少（最多1根）
4. Material Characteristics of TBR tire components. 全钢子午胎构件材料的特性
