Can a small tire bulge be repaired?

It can be repaired, but it is recommended to directly replace it with a new tire. Even if the tire bulge is repaired, there is still a risk of tire blowout. A tire bulge occurs when the cord layer on the sidewall of the tire is damaged. It's important to know that this layer supports the entire tire's expansion and contraction. Once the steel wires inside are broken, the tire loses its protection, making it highly susceptible to blowouts. Below are the reasons for tire bulges: 1. Tire aging: If a tire is used for too long and exceeds its warranty period, it may age. Hitting a stone or speed bump while driving can cause a bulge. 2. Excessive tire pressure: Overinflated tires reduce the contact area with the ground, leading to premature wear. During use, rapid acceleration or poor tire heat dissipation can cause the tread temperature to rise, resulting in a bulge. If your tire has a bulge, it is advised not to continue using it. A bulged tire cannot be repaired or patched because the cord layer inside may have fractured. Even if repaired, the bulge may reappear after some time, posing a serious risk of blowout and creating significant hazards for vehicle operation.
I have some knowledge about cars and have encountered similar issues before. A tire bulge, even a very small one, is generally not repairable. This is because there are fabric layers inside the tire, acting like a skeleton to support it. Once a bulge appears, it means those layers are broken or damaged. Repairing the surface of the tire is useless because the internal structure is already compromised. When driving, the tire experiences uneven forces, which could lead to a blowout, especially at high speeds—this is extremely dangerous. It's recommended to go directly to a professional tire shop to replace the tire. Although it costs more, safety comes first. Regularly checking tire pressure and avoiding potholes can also reduce the likelihood of bulges.
As someone who drives frequently, I've encountered similar situations. No matter how small a tire bulge is, it can't be repaired. When there's severe internal damage, repairs are just superficial and don't address the real issue. Tires endure tremendous pressure while rolling, and even a tiny flaw can rapidly worsen under high temperatures or speeds, potentially leading to a blowout and accidents. I strongly advise against taking this risk—consult a tire specialist immediately to determine if replacement is necessary. Additionally, avoid overloading or driving on gravel roads, and remember that regular maintenance is far more cost-effective than dealing with the aftermath.
