Is it a problem if there's a small bulge on the side of the tire?
1 Answers
When a tire bulges, it indicates that the internal cord layers are damaged. Since cord layer damage is irreparable, a bulging tire should not continue to be used and must be replaced promptly to prevent the risk of a blowout. Here is more relevant information: 1. Causes of tire bulges: A tire bulge occurs when the internal cord layers are damaged, causing uncontrolled air pressure inside the tire, which leads to uneven force distribution on the outer tire. Areas under higher pressure will protrude, forming a bulge. This is a common type of tire wear. If not addressed promptly, the bulge can suddenly rupture due to rolling acceleration or excessive friction heat, leading to an explosion. Statistics show that the vast majority of blowouts are caused by bulges. 2. Irreparability: Whether it's a bulge or a sidewall rupture, neither can be repaired by patching. The cord layers in these areas are already broken, and patching only involves applying a rubber piece inside, which cannot fully restore the cord layers. As a result, after some time of driving, the tire may bulge again in the same spot or even blow out, posing significant safety hazards. Additionally, the sidewall of a tire is constantly deforming and recovering while driving, making patches prone to falling off. The best solution is to replace the tire promptly.
