What Causes Tire Bulges?
2 Answers
Tire bulges can occur due to the following reasons: 1. Tire bulges are caused by excessive internal pressure. 2. If the sidewall of the tire is impacted during driving, the sidewall fabric may rupture, allowing outside air to enter the tire and causing a bulge. The following situations indicate that a tire cannot be repaired: 1. Damage to the sidewall cannot be repaired. 2. A puncture in the tread with a diameter exceeding 6 millimeters cannot be repaired. 3. Damage such as bead damage or deformation, tread deformation, rubber corrosion by chemicals, or damage from driving under-inflated cannot be repaired. 4. The tire has a bulge.
Tire bulges are really a headache, and I've encountered this issue myself before. The main causes are often tire aging, where the cord layers start to crack after years of use, allowing internal pressure to seep out through these gaps and form bulges. If you're not careful about potholes or curbs while driving, hitting them can also break the cords and cause bulging. Large temperature fluctuations can accelerate this process, such as high summer temperatures softening the tire material. Once a bulge appears, don't take it lightly—it could burst at any moment, leading to loss of control. I recommend checking tire pressure and appearance monthly, especially before long trips. Also, avoid parking in direct sunlight to extend tire life.
