What does tire ply rating mean?

[NaomiFitz]

Tire ply rating is a concept of strength. Introduction to tires: Tires are circular elastic rubber products mounted on various vehicles or machinery for ground rolling. They are typically installed on metal rims to support the vehicle body, cushion external impacts, ensure contact with the road surface, and maintain the vehicle's driving performance. Tires often operate under complex and demanding conditions, enduring various deformations, loads, forces, and high or low temperatures during use. Therefore, they must possess high load-bearing capacity, traction performance, and cushioning properties. Functions of tires: To reduce and absorb vibrations and impact forces during vehicle operation, preventing early damage to automotive components caused by severe vibrations. Additionally, they adapt to high-speed driving conditions, reduce driving noise, and ensure safety, comfort, handling stability, and fuel efficiency.
