Are There Steel Wires Inside Tires?
1 Answers
Modern car tires do not have steel wires in their sidewalls. More details are as follows: 1. Materials: Current manufacturing processes use nylon or polyester cords woven into a mesh. Nylon cords make the tire lighter and more elastic. 2. Steel belt layer: Modern tires do have a steel belt layer, but it is located beneath the tread and embedded in rubber, not in the sidewall. A steel wire bead is present at the rim joint area to maintain the inner shape and form a seal with the rim. The so-called radial-ply structure refers to the tire body's fiber arrangement radiating from the center point at a 90-degree angle to the wheel's longitudinal axis, forming a single-layer structure.
