Is a bulge on the tire serious?

[McRonan]

Automobile tire bulges are serious and should be replaced promptly. The main causes of tire bulges are as follows: 1. Crown separation: Crown separation mainly manifests as delamination at the top of the tire tread (referred to as the crown surface). The primary reason is excessive tire pressure during use, which reduces the tire's contact area, leading to early wear. During operation, rolling acceleration or poor heat dissipation causes the tread temperature to rise. The adhesion between the cord layers decreases, and the increased centrifugal force on the tread causes crown delamination. 2. Shoulder separation: Shoulder separation is a type of sidewall bulge, divided into local and overall types, commonly found between the tire tread and sidewall. It mainly appears as noticeable bulges, resembling bubbles! Some may be ring-shaped, indicating complete separation! The sidewall and tire body are clearly detached. This is caused by insufficient drying of the cord during the tire manufacturing process before rubber coating, or excessive moisture content in the rubber itself, which is a quality issue.

A bulge on the tire is definitely serious and should never be ignored. I’ve encountered a similar situation before—tire bulging usually occurs due to broken internal cords, often caused by hitting potholes or curbs, which significantly weakens the tire's structural integrity. At high speeds, uneven pressure can easily lead to a blowout, especially during overtaking or turning, making it even more dangerous. It’s recommended to stop and inspect immediately. If you’re still on the road, drive slowly to a safe spot and switch to the spare tire. Then, visit a professional repair shop as soon as possible for inspection and replace the tire if necessary. Tires are the foundation of driving—small issues can escalate into major hazards, so safety should always come first. Make it a habit to regularly check tire wear and pressure to prevent such problems. Don’t delay repairs or replacements to save money—the cost is always far less than the potential losses from an accident.

I've been researching tire issues for a while. Tire bulges are usually caused by damage to the cord layers, often due to driving too fast over hard objects or tire aging. This creates localized pressure points, posing an extremely high risk of blowouts at high speeds with potentially catastrophic consequences. Take action now: After parking safely, confirm the bulge location and don't attempt long-distance driving. Immediately contact a nearby tire shop for replacement - don't just choose cheap off-brand options, go for OEM or reliable brands for peace of mind. Test drive after replacement to check stability. This damage is irreversible, and delaying will worsen the tire's condition, affecting braking distance. Develop a habit of monthly tire pressure and tread checks to catch small issues early.

My car had a bulge last year too, which scared me into dealing with it immediately. A tire bulge indicates internal structural damage, which can't be repaired. You'll feel obvious wheel shaking while driving. If ignored, it could lead to loss of control or a blowout during high-speed turns, especially on rainy days when it's more slippery. Once noticed, slow down and stop immediately—don't push your luck. Schedule a visit to the repair shop and let the mechanic confirm if a tire replacement is necessary. Be careful not to damage the rims during the process. Addressing it promptly ensures safety—I’ve been through it myself, and the car runs smoothly with new tires. Next time, pay attention to road conditions and avoid potholes. Simply put, small bulge, big danger—don’t cheap out on fixing it.
