What are the possible causes of car tire fires?
3 Answers
Car tires are made of rubber and do not normally catch fire during regular driving. However, when exposed to high temperatures, friction, emergency braking, towing, and other similar conditions, a significant amount of heat energy can be generated. If the tire reaches its ignition point, it may catch fire. Below are some relevant details: Exposure to open flames: Ensure that you do not intentionally expose tires to open flames. If a tire comes into contact with an open flame, especially in the presence of gasoline, it will certainly ignite. Excessive friction: Additionally, when driving your car, try to avoid prolonged or overly aggressive braking on long downhill slopes. Excessive friction between the tire and the road surface can generate too much heat, causing the tire to reach its ignition point. If the tire's temperature is not promptly reduced, it may result in spontaneous combustion.
I've been driving for decades and have seen tires catch fire several times for various reasons. The most common cause is brake system malfunctions, especially when drum brakes overheat and ignite the tire rubber; excessive friction heat during high-speed driving, particularly with overloaded vehicles more prone to spontaneous combustion; external fire sources like fuel or oil leaks dripping onto the tires; severely worn tires or insufficient air pressure leading to increased deformation and heat; high summer road temperatures or prolonged parking causing elevated hub temperatures, making accidents more likely. For prevention, I always emphasize checking tire pressure regularly, maintaining the brake system, avoiding sudden braking or acceleration while driving, and pulling over immediately if unusual noises or smoke are detected. Safety first—it's always good to keep a small fire extinguisher in the car.
Tire fires are something to be really careful about! Friction is the main cause, such as overheating brakes on long downhill slopes; severe tire wear or punctures causing internal sparks; external factors like oil leaks coming into contact with hot engines igniting fires; especially prone during high-temperature periods in summer. For prevention, I regularly check tread wear, maintain standard tire pressure, and avoid overloaded driving. Pay attention to unusual noises during high-speed driving, and feel the wheel hub temperature when parked. Also, avoid storing flammable materials near tires, and be mindful not to carelessly discard cigarette butts when smoking. Simple habits can save lives—why not adopt them?
