Can a puncture on the sidewall of a tire be repaired?
1 Answers
Tire sidewall punctures can be repaired if the radial length of the scratch is less than 5cm and the axial length is less than 0.5cm. Generally, if more than three layers of the tire sidewall cord fabric are broken, it is not recommended to repair it as it may affect driving safety. If the number of broken cord fabric layers is three or fewer, the tire can still be repaired. Below is some relevant information about car tires: 1. Most car tires are radial tires, primarily composed of cord fabric layers and rubber. The cord fabric layers consist of horizontal and vertical cord threads (some may include steel wire mesh), which mainly bear the load, while the rubber provides sealing and flexible deformation functions. 2. When a tire is punctured and leaks air, it is usually due to damage to the tire's inner liner, which can be repaired. However, if the cord fabric layers are damaged, it directly affects the tire's strength. The more cord threads that are broken, the greater the risk of a blowout. Similarly, if the inner cord threads of the tire are not broken, the tire can still be used normally after restoring its airtightness.
