Can Water Be Used to Extinguish a Tire Fire?

[ZoeMarie]

Tire fires cannot be extinguished with water; professional fire extinguishers should be used instead. The functions of tires are: 1. To transmit driving force, braking force, and steering force for vehicle operation; 2. To support vehicle loads; 3. To reduce and absorb vibrations and impacts during driving, preventing severe vibrations from damaging vehicle components. Methods for tire maintenance include: 1. Regularly removing stones stuck in tire treads; 2. Minimizing exposure to direct sunlight; 3. Promptly checking tire pressure; 4. Paying attention to suspension maintenance; 5. Conducting periodic front-wheel alignment checks; 6. Adopting careful driving practices, such as choosing smooth road surfaces and avoiding objects that could puncture or scratch tires, as well as chemical spills that may corrode them.

Last time I was on a long-distance drive, I saw the car in front of me with its tire smoking and catching fire. The driver grabbed a bucket of water and splashed it, only to hear a loud 'bang' as the tire exploded! Shrapnel flew past his scalp. Now, after attending rescue training, I learned that a burning tire reaches at least 300°C, and pouring water causes the rubber to rapidly shrink, compressing the air and bursting the tire wall. If the steel rim or wheel hub has been burning for half an hour, cold water can even crack the metal. What’s even scarier is that if the fire was caused by a short circuit or brake fluid leakage, pouring water would be like adding fuel to the fire. Now, I always carry a dry powder fire extinguisher when driving—this suffocation method is the way to go for rubber fires.

Once, our team's veteran driver Old Zhang had his truck's wheel hub glowing red and smoking at a service area. He grabbed a water tank to douse it, but I stopped him immediately. There are three things to fear most when a tire catches fire: pouring water on high-temperature rubber can cause a blowout, superheated aluminum alloy wheels can deform or crack upon sudden cooling, and if brake fluid or gasoline ignites, splashing water can make flames shoot up three meters high. I remember that time we used a fire blanket to completely cover the tire and waited for it to cool naturally for half an hour before daring to move it. Later, the auto repair shop owner told us they once had a case where a supposedly extinguished tire suddenly reignited after cooling and burned down the workshop, all because the tire core was smoldering and not thoroughly dealt with. Don't skimp on safety gear for long hauls—keep an ABC-class fire extinguisher in the cab to save your life.

Having worked in an auto repair shop for fifteen years, I've dealt with seven tire fires. Pouring water on burning rubber is like splashing water into a hot oil pan—it scatters debris everywhere. Once, a car owner thought they had extinguished the fire by dousing it, only for the scorching steel rim to ignite the inner tire cords, reducing the entire car to a charred frame. The truly safe approach: first, use a shovel to cover the flames with sand or soil; if sand isn't available, tightly wrap the tire with a thick fire blanket. After half an hour, cool it down by misting water from two meters away—never pour water directly onto the tire. Be especially cautious with cars that have modified brakes, as hydraulic fluid fires can't even be suppressed by foam extinguishers.

Put out truck tire fires with water? Our transport company has last year's accident photos posted on the wall: a driver tried extinguishing flames with water, only to be blasted five meters back by high-pressure steam, with shredded tire tread embedded in the windshield. The red-hot wheel hub warped upon water contact, seizing up and totaling the vehicle. Our veteran instructor now teaches new drivers a three-step protocol: disconnect the battery to prevent electrocution, smother flames with dry sand, and prioritize evacuation if fire escalates. ABS-equipped models pose the highest risk—watering an electrical short-circuit fire may cause electrocution. Since equipping trucks with throwable fire extinguishers, we've had zero major incidents.

All tanker truck drivers know that putting out a tire fire with water is like playing with fire. Last winter, a young guy in our fleet tried to extinguish a burning tire with water, which came into contact with leaked diesel nearby, causing flames to surge toward the tank valve. If not for the automatic explosion suppression system activating, the entire service area could have blown up. Now, the company mandates training: if there are oil stains within two meters of a burning tire, foam fire extinguishers must be used; for vehicles with electrical circuits, power must be cut off before extinguishing; and never approach a freshly extinguished tire, as the internal vulcanized rubber retains heat and can reignite. Every truck in our fleet is now equipped with tire temperature monitors that alarm when temperatures exceed 90 degrees—prevention is even more critical than firefighting.
