What Does Tire Cord Look Like?
2 Answers
Tire cord is a fabric woven from chemical fiber threads. During tire manufacturing, a layer of rubber is applied and then a layer of fabric is wrapped around it to form the tire shape. Here is some information about tire cord: 1. The rubber-coated cord fabric used in tires is located in the tire carcass, forming the single or multiple layers of rubber-coated cord that constitute the tire skeleton. It requires good impact resistance and flex resistance. The carcass cords are wound around it, and the area that connects with the rim is composed of bead wires and rubber. 2. Cord fabric is only used in semi-steel radial tires and cannot be used in all-steel or bias-ply tires.
When repairing cars, I often cut open tires to study their internal structure. The cords are there, usually layered fabrics resembling fine nylon cloth or fiber mesh densely distributed. They are not visible from the outside; you have to peel back the rubber to see their full appearance. The material is mostly polyester or nylon threads woven into a mesh, sturdy yet flexible, and feels slightly rough to the touch. When tires age or are cut by sharp objects, the cords can become exposed, protruding like frayed edges in a fibrous manner, which increases the risk of bulges or blowouts. As a professional, I emphasize that cords are the skeleton of a tire, directly impacting driving stability and durability. Regular maintenance, such as monitoring tire wear and pressure, can indirectly assess the condition of the cords. Modern tires also use steel cords to enhance load-bearing capacity, a design that is safer and more reliable than older models.
