What Causes Tire Bulging?
2 Answers
Tire bulging is caused by: 1. Driving over potholes at high speed; 2. Quickly running over protruding obstacles; 3. Mounting curbs at a small angle; 4. Quality issues with the tire itself. Tires are crucial components of a vehicle, and their functions include: 1. Supporting the entire weight of the vehicle, bearing the load, and transmitting forces and moments in other directions; 2. Transmitting traction and braking torque to ensure good adhesion between the wheels and the road surface; 3. Improving the vehicle's power, braking, and off-road capabilities, working with the suspension to mitigate impacts during driving and dampen resulting vibrations; 4. Protecting vehicle components from severe vibrations and premature damage; 5. Adapting to high-speed performance and reducing driving noise; 6. Ensuring driving safety, handling stability, comfort, and fuel efficiency.
I've been driving for almost ten years, and tire bulges are really not uncommon. The most common cause is accidentally hitting potholes or curbs while driving—the sudden impact is too strong, causing the inner cord layers of the tire to tear or separate, resulting in a bulge on the sidewall. Tire pressure is also crucial; too high or too low is bad. Low pressure means insufficient sidewall support, making it prone to deformation when hitting obstacles, while high pressure reduces elasticity and can also cause bulges. Another issue is tire aging—after four or five years, the rubber becomes brittle, and hot weather accelerates this process, weakening the tire and making it more prone to problems. When driving, pay attention to the road surface, slow down when encountering bumps, and avoid overloading the car to reduce tire stress. Check the tire pressure monthly to maintain the standard level. If you notice a bulge, don’t take chances—replace the tire immediately, as a high-speed blowout is extremely dangerous.
