What are Bias Ply Tires?

[ArthurRose]

Bias ply tires are also known as conventional structure tires. They refer to pneumatic tires where the carcass plies and breaker layers have adjacent ply cords that intersect and are arranged at an angle of less than 90 degrees to the centerline of the tread. This type of tire offers excellent longitudinal rigidity and is suitable for high-speed driving on regular road surfaces. Below is relevant information about bias ply tires: 1. The role of materials selected for bias ply tires: When high-strength cord materials such as nylon, polyester fiber, or steel wire are used, the load-bearing capacity of the tire can be significantly improved, enhancing its performance. These tires are commonly used in modern vehicles. 2. Composition of bias ply tires: Bias ply tires mainly consist of the tread, plies, breaker layers, and bead. In conventional bias ply tires, the adjacent plies and breaker layers intersect and are arranged at an angle of less than 90 degrees to the tread centerline. The tread pattern of bias ply tires is cross-shaped, providing anti-slip properties. However, since the inner layers remain unchanged, the economic benefits are not significant.
