What Causes Tire Bulging?

Tire bulging can be attributed to the following reasons: 1. Impact or compression at the bulging area: The most common cause is when a car hits a curb at high speed or at an inappropriate angle. In such cases, there are usually signs of impact, such as scratches on the surface or white impact marks inside the tire at the bulging area. Careful inspection will reveal subtle differences. 2. Tire quality issues: One scenario is when the fabric cords inside the tire have quality defects, leading to insufficient local strength; another is when the joints between the cord layers are poorly processed. Bulging caused by quality issues will show no marks on the tire surface or inside at the bulging area. 3. Insufficient structural strength in low-cost tires: The tire market is highly competitive. To reduce costs, low-cost tires may use fewer layers of fabric or nylon or inferior-quality cord layers, compromising the tire's strength. Even minor impacts can cause bulging in such tires.

I've experienced tire bulges several times. It usually happens when the tire hits a pothole, curb, or stone, causing the inner cord fabric to tear or break, resulting in a bulge on the surface. Additionally, as tires age, the rubber becomes brittle and hard, making them more prone to damage from minor impacts. When tire pressure is too low, the sidewalls bear uneven stress, and repeated deformation can lead to bulging. I made the mistake myself last time—I noticed it on the highway and had to pull over to change the tire immediately; otherwise, the risk of a blowout was very high. My advice is to avoid rough roads when driving, check tire pressure weekly to maintain the standard level, and replace any problematic tires without hesitation—safety always comes first.

A bulging tire often hides potential safety hazards. I always remind myself to drive carefully because a single accidental impact—like scraping against a curb—can damage the tire's sidewall structure. Aging tires are more prone to this issue, as high temperatures and wear make the rubber brittle. If left untreated, the bulge can expand, overheat, or even burst during high-speed driving—just thinking about it sends chills down my spine. I must emphasize: don’t wait for an accident to act; if you spot a bulge, head to a repair shop for a tire replacement. Meanwhile, develop good habits: avoid sharp turns that stress the wheels and schedule regular maintenance to check tire pressure. For the sake of your loved ones, these details shouldn’t be overlooked.

I encountered tire bulging during my novice period, which turned out to be caused by broken internal tire cords leading to protrusions. Common reasons include hitting potholes or insufficient pressure; rubber aging also plays a part. The mechanic said this issue can easily lead to tire blowouts and recommended immediate replacement without delay. Since then, I've changed my habits: I take a quick look at the tire's appearance before driving. Prevention is always more cost-effective than repairs and saves a lot of hassle. Now, I pay more attention when road conditions are poor and address any issues early.
