What are the causes of tire bolt breakage?
3 Answers
Tire bolt breakage can be caused by: 1. Vehicle overloading; 2. Improper tire reinstallation method; 3. Damage to the tire rim bolt holes or incompatibility with the original vehicle specifications; 4. Foreign objects trapped between dual wheels; 5. Excessive tightening force; 6. Tire dimensions exceeding allowable specifications. Tires are circular elastic rubber products mounted on metal rims, designed to support the vehicle body, cushion external impacts, maintain contact with the road surface, and ensure driving performance. Precautions for tire usage include: 1. Monitoring tread wear patterns; 2. Avoiding excessively high or low tire pressure; 3. Removing debris from tread grooves to prevent punctures that may lead to air leaks or blowouts; 4. Regular tire rotation to prevent uneven wear.
Tire bolt breakage is quite common. Once when I was on the highway, I suddenly felt the car shaking violently. After getting out, I found a bolt had broken, nearly causing an accident. There are many reasons for this, such as over-tightening the bolts. If tools are used with excessive force during repairs, the internal stress on the bolts becomes too high, making them prone to cracking. Corrosion is also a major issue, especially in areas with heavy rainfall. Rust and corrosion weaken the bolts over time, leading to eventual breakage. Material fatigue is another hidden danger. After prolonged use, bolts undergo repeated stress, much like metal fatigue, gradually wearing out their lifespan. Improper installation is also a factor, such as misalignment when fitting new tires or using substandard accessories, causing uneven stress on the bolts. Vehicle overloading is another cause, as excessive weight increases tire pressure and puts additional strain on the bolts. This issue is very dangerous, so it's essential to pull over immediately and check. During routine maintenance, always ask the mechanic to inspect the bolt condition to avoid negligence.
The causes of broken wheel bolts are commonly seen in repair work, with over-tightening being the most frequent mistake. Many people use pneumatic tools to apply excessive pressure on the bolts, leading to internal stress cracks. Corrosion should not be overlooked either; bolts rust on roads with high salt content or in humid weather, weakening the structure and increasing the risk of breakage. Metal fatigue is a long-term issue, as bolts undergo frequent stress deformation from prolonged vehicle use, eventually failing. When a vehicle is overloaded, the tires bear extra weight, doubling the stress on the bolts and accelerating damage. Mismatched parts, such as using non-original bolts of incorrect size, can also cause uneven load distribution. For prevention, it is recommended to regularly inspect bolts for cracks or signs of corrosion and use a torque wrench during replacement to avoid excessive force.
