Is there a bulge on the sidewall of the tire?
3 Answers
Tire bulges require replacement, whether they occur on the sidewall or the tread, as they pose a risk of blowout and should not be used further. A bulging tire indicates that the internal cords have broken. The cord layer is the skeleton of the tire, and if the cords break, only the rubber remains to prevent air from escaping. Additionally, the sidewall is inherently weak, so when the tire pressure is too high, the bulging area is prone to rupture. The following conditions make a tire unrepairable: 1. Damage to the sidewall cannot be repaired. 2. A puncture hole in the tread with a diameter exceeding 6 mm cannot be repaired. 3. If there is damage or deformation to the bead, tread deformation, rubber corroded by chemicals, or damage caused by running the tire flat, it cannot be repaired. 4. The tire has a bulge.
The other day when I was driving over a bumpy road, I felt something was wrong. Upon checking, I noticed a bulge on the sidewall of my tire. As someone who's been driving for over a decade, I'm all too familiar with this—it usually happens when the tire hits a hard object like a curb or pothole, causing the inner cord layers to break and air to squeeze out, forming a bulge. The sidewall is the weakest part of a tire, and there's no way to repair it—you must replace the tire immediately, otherwise a blowout at high speed could be disastrous. I still remember a friend who stubbornly kept using a bulging tire, and it ended up blowing out, nearly causing an accident. So it's better to spend the money on a new tire than to take the risk. Regularly checking tire pressure and avoiding obstacles can help prevent this issue. If you find a bulge, it's best to drive to a professional shop for evaluation rather than trying to dismantle it yourself.
If you notice a bulge on the sidewall of your tire, don't hesitate—stop driving immediately. I've seen many cars experience blowouts because of this, especially on highways, which is extremely dangerous. The cause is usually the tire suffering an impact, possibly from hitting a pothole, curbing the wheel, or internal breakage due to aging. The sidewall is weak; once it bulges, the tire is done—it can't be repaired, only replaced. I recommend going straight to a repair shop to have them check if the wheel rim and tire pressure are normal. Always pay attention to road conditions while driving to avoid hard impacts, and maintaining proper tire pressure can reduce risks. Tires are a crucial part of your vehicle—safety first, don't skimp on a few hundred bucks.
