Modern tires are manufactured using advanced technologies from wear-resistant materials. Additionally, each tire is tested for resistance to mechanical and thermal stress. But actual operation makes adjustments to the design characteristics of the tires.
Causes that lead to tire explosion
You need to understand that a well-known brand and a high cost of a tire do not guarantee that it will not burst at speed. There are many reasons for this kind of trouble. For example, a driver ran over tram tracks at an impressive speed. As a result, the cords broke, and a bulge or a so-called “bump” was formed on the sidewall. If it crawled out on the inside of the wheel, then it is almost impossible to notice it.
Ideally, such a tire should be replaced. But there are craftsmen at the services and tire fitters who eliminate the “bump” with the help of a cord plaster. The technology provides for a certain algorithm of actions, after which the tire can be installed on the car, but only on the rear axle. If the bump goes unnoticed, then under the influence of the load, it can explode at any moment.
When buying used rubber, it is necessary to inspect the inner surface for the presence of cord plasters. Installing them indicates that there was a bump or side cut on the tire.
Another common cause is extreme wear and tear combined with overheating. The desire to save money on car tires makes you drive it to the last. It happens that the tire wears out so much that the sipes are practically not visible. People jokingly call such a tire “slick”, hinting that the driver is preparing for Formula 1 races.
Not only does bald rubber lose grip on the asphalt – it becomes more vulnerable to damage. Even hitting a glass bottle can cause an explosion. In addition, it is worth remembering that at a speed of 100 km / h the tire heats up to 160 degrees Celsius, and even more in summer. Accordingly, the pressure rises sharply, and with it the risk of an explosion on the go.
Valves are dangerous factors. Its edges, sticking out of destroyed curbs and slabs, instantly turn even a new tire into rags. Moving deep holes leads to the same effect. It is important to remember that the engine and attachments place additional stress on the wheel and therefore increase the risk of explosion.
What Happens When a Tire Explodes
When a tire bursts, the driver, passengers and others hear a loud bang. If this happens, a turning force is formed, which throws the car onto the side of the road or into the oncoming lane. It is especially dangerous for SUVs due to their high profile and massive rubber.
Low profile tires, thanks to a stiffening strip or bumper that runs around the entire circumference closer to the disc, reduces the turning force. Accordingly, the most dangerous are high-profile tires, which are installed mainly on SUVs.
What not to do if a tire blows up
Reflexively, the driver begins to turn the steering wheel abruptly in the direction opposite to the chaotic movement of the car. The second incorrect action is pressing the brake pedal. The combination of these moments creates an even greater unfolding force. And if the car is carrying sideways, the curb can cause the car to roll over. Certain problems in this case are created by the ABS system, which also locks the wheel.
Rule of conduct if a tire bursts
If a tire blows up at speed, stay calm, do not make sudden movements. The first task is to hold the steering wheel, make the car continue to move in a straight line (as far as possible). Electric or hydraulic power steering will help with this. In fact, even without one tire, the car retains handling and stability.
The next step is to gradually slow down by gently depressing the brake pedal. The final stage is to carefully taxi to a safe area and stop to install a spare tire or call a tow truck. So, understanding nature, correctly assessing risks and performing simple actions will save you from injury and material damage.
