What Are the Causes of Tire Bulges?

[StChloe]

Tire bulges are caused by: 1. External impact; 2. Quality issues with the tire itself. The functions of tires are: 1. To transmit driving force, braking force, and steering force for vehicle operation; 2. To support vehicle load; 3. To reduce and absorb vibrations and impacts during driving, preventing severe vibrations from damaging vehicle components. Tire maintenance methods include: 1. Regularly cleaning out stones stuck in tire treads; 2. Minimizing exposure to direct sunlight; 3. Promptly checking tire pressure; 4. Paying attention to suspension maintenance; 5. Regularly inspecting front wheel alignment; 6. Adopting proper driving techniques, such as choosing smooth road surfaces and avoiding objects that could puncture or scratch tires, as well as chemical spills that may corrode tires.

I've thought about tire bulges quite a few times, mainly it's due to broken internal cord layers. Think about it, those fine fabric cords inside the tire are like steel reinforcements supporting the entire structure. If you accidentally hit a curb or pothole at high speed while driving, the cord layers get damaged by the impact, making it prone to bulging. Also, tire aging over time is a big issue - materials become brittle and hard with age, making them vulnerable to damage from minor impacts. Improper inflation (either too high or too low) worsens the situation by causing uneven stress distribution. After bulging, the sidewall becomes thinner, creating significant risk of blowouts during high-speed driving that threatens everyone in the vehicle. My habit is to walk around the car to inspect tires before every trip, replacing any with cracks or bulges immediately. I also drive carefully to avoid obstacles - saves money and prevents injuries. After all, tires are the foundation of driving - never take them lightly.

I have over a decade of driving experience and have personally encountered tire bulges. The most common cause is driving too fast over potholes or curbs, where the tire suddenly hits a hard object, impacting the cord layers and causing internal breakage and deformation. Another time, the tire sidewall became brittle due to aging, and even small, usually insignificant stones could cause a bulge. After a bulge forms, the tread might look fine, but the sidewall protrudes significantly, causing severe shaking and anxiety at high speeds. Learning from these experiences, I now make it a habit to regularly check tire pressure and wear conditions, and inspect for any abnormalities before long trips. I recommend everyone adopt this practice—safe driving starts with attention to detail and can save a lot of trouble. Well-maintained tires provide peace of mind and confidence on the road.

Tire bulges must never be taken lightly, as they are mostly caused by accidentally hitting potholes or obstacles that damage the internal cord structure, or by tire aging leading to reduced strength. A bulge indicates weakened sidewalls, which can easily lead to a blowout—a particularly dangerous situation. Safety first: if you notice a bulge, replace the tire immediately without hesitation. When driving, always avoid potholes and slow down over speed bumps. Regularly check your tire condition to ensure driving safety.
