What are the causes of tire bulging?
4 Answers
The causes of tire bulging are: 1. The sidewall of the tire is squeezed by hard objects, causing the sidewall cords to break; 2. Quality issues with the tire. The maintenance methods for tires are: 1. Regularly clean the stones in the tire tread; 2. Reduce exposure of the tires to direct sunlight; 3. Promptly check the tire pressure; 4. Pay attention to the maintenance of the suspension. The functions of tires are: 1. Support the entire weight of the vehicle and bear the load of the car; 2. Transmit traction and braking torque, ensuring the adhesion between the wheels and the road surface; 3. Reduce and absorb vibrations and impacts during driving, preventing severe vibrations and early damage to car components; 4. Adapt to the high-speed performance of the vehicle and reduce driving noise, ensuring safety, handling stability, comfort, and fuel efficiency.
Once while driving, I suddenly noticed a bulge on the sidewall of my tire, which gave me quite a scare. Tire bulges usually occur when the sidewall suffers severe impact, such as hitting deep potholes, curbs, or rocks, causing internal cord breakage. Another cause is prolonged tire aging, where the rubber becomes brittle. Insufficient tire pressure also makes tires more susceptible to damage. I remember last time on the highway, I didn’t pay attention to the road and ran over a large rock, and the next day a bulge appeared. Actually, this issue is extremely risky—once a bulge forms, it can lead to a blowout, especially dangerous at high speeds. It’s advisable to stay vigilant while driving, avoid uneven road surfaces, regularly check and maintain proper tire pressure, and avoid overloading. Regular tire inspections are essential; replace them at the first sign of minor cracks, don’t wait until bulges appear.
As a car enthusiast, I've studied tire structures and found the sidewalls are the thinnest part, relying on internal cords for support. Bulges occur when these cords get damaged: commonly from hitting sharp objects or potholes while driving, causing instant impact that tears the fibers; when tires reach their lifespan, aged rubber loses elasticity and cracks from minor bumps; improper tire pressure also contributes - too low causes excessive flexing and internal friction. I learned this the hard way when driving too fast on mountain roads, where heat expansion caused significant pressure fluctuations. Side note: harsh weather or rough roads accelerate wear, making cords more prone to fatigue fractures. Developing good habits prevents issues - like checking tire pressure monthly and slowing down for obstacles. If a bulge does appear, don't risk driving; getting a new tire at a repair shop is the safest approach.
I think the key to tire bulging is external damage plus internal aging. When hitting curbs or stones while driving, the impact point on the sidewall damages the cord layers, causing localized swelling; tires become brittle after years of use and can't withstand impacts, leading to issues; unstable tire pressure also contributes significantly. This is very dangerous as it directly weakens tire strength, drastically increasing the risk of a blowout. Remember to drive slowly on flat roads and avoid prolonged driving that heats up and expands the tires. It's recommended to have regular professional inspections, ensure tire pressure meets standards, and replace tires when needed without delay.
