Which component is responsible for giving a tire its tensile strength and maintaining shape?

The cord body is crucial for a tire's tensile strength and maintaining its shape. This component is made up of layers of fabric and steel cords that provide structural integrity, allowing the tire to withstand various stresses such as pressure from inflation, friction with the road surface, and impacts from obstacles.

The cord body also plays a significant role in the overall performance and durability of the tire, as it helps distribute the load evenly while enhancing stability during operation. Without the cord body, the tire would lack the necessary strength to function safely and effectively under normal driving conditions.

Other components like the tread and sidewall serve important functions, such as providing traction and protecting the internal structure, while the beads secure the tire to the rim. However, it is the cord body that fundamentally provides the strength and shape-retaining characteristics essential for a reliable tire.
