Flat tires can lead to accidents - things you must be aware of

The surface temperature in summer reaches dozens of degrees, which has entered the high incidence period of tire blowouts for trucks weighing several tens of tons driving fast on the highway. If the tire blowout is not properly rescued, it easily leads to a car crash. Data shows that about one-third of the traffic accidents on highways are caused by tire failures, with the main one being tire blowouts. So, what are the reasons for truck tire blowouts?

The temperature in summer is already high, and the road surface will be even higher after being exposed to the sun. Rapidly moving trucks, tires and road friction will make the tire temperature continues to rise, directly leading to a gradual increase in air pressure in the tire. This is coupled with the frequent braking required by the vehicle, which generates heat that also contributes to higher temperatures. Tire pressure that is too high increases the likelihood of a blowout.

So, is it useful to deliberately lower the tire pressure in summer to avoid tire blowouts caused by high temperatures? Obviously, it is not. Because tires with insufficient pressure will be constantly squeezed and deformed during high-speed driving, also producing a large amount of heat, which can lead to tire bias grinding or even tire blowouts.

Trucks that often operate in harsh working conditions are prone to bulging, cracking, and other external injuries in the tires, which also increases the chances of a tire blowout. Especially in trucks transporting from mines or construction sites. Timely cleaning should be done to avoid the danger of a tire blowout.

Overloading causes the actual load to exceed the load index of the tire, and when inflating the tire it is often inflated with 2-4 more air pressures than normal. In the high temperature and fast driving process, tires are overloaded for a long time, it is easy to have a flat tire.

Tires, as a vulnerable part of trucks, are prone to excessive wear for a variety of reasons. When the tire tread has been worn flat or bias grinding is very serious, the tire's load capacity and compressive strength has been far lower than normal tires. If not replaced in time, under the influence of factors such as high temperature, speeding and road bumps, it is easy to have a tire blowout.

If you find that the temperature of your tires is too high or the tire pressure is abnormal while driving, you should stop at a service area to rest and wait for the temperature to decrease before continuing to drive. Using the method of splashing cold water to cool down can easily cause changes in the internal structure of the tire due to sudden cooling, accelerate tire damage, and may lead to a blowout.

If a cooling water system is installed for the brake system, it is recommended not to wait until the tire temperature rises before turning on the water to cool it down. If the tire temperature is too high to use water to cool it down, when the temperature outside the tire drops causing rubber contraction, while the tire still maintains a high internal temperature and pressure, the tire inside and outside are subjected to different forces, making it very easy to cause a blowout.

A flat tire while in transit is likely to result in a serious accident if improper measures are taken. Below we will provide you with a few references to deal with a flat tire during transportation.

If the steering wheel of the vehicle has a flat tire, the vehicle will instantly lose its direction. Therefore, after the steering wheel tire bursts, hold the steering wheel immediately, wait for stability, then slowly brake and drive away from the main road. During this process, do not repeatedly turn the steering wheel sharply, nor brake suddenly; after stopping, place a warning triangle upright behind the vehicle to prevent secondary accidents.

A trailer tire blowout is less dangerous than a steering wheel blowout. The driver just need to hold the steering wheel and then repeatedly step on the brake pedal. This will shift the center of gravity of the vehicle forward, so that the intact front tire force, reduce the pressure on the tire after the burst.

The above are all reasons for tire blowouts that occur when the vehicle is in motion, and many tire blowouts also occur during maintenance and inflation. When inflating the tire, be sure not to exceed the tire's rated air pressure, as many cases result from not carefully checking the tire and then over-inflating it, leading to a blowout. Additionally, when inflating the tire, the tire should be secured in a safety device, and maintenance personnel should stay away to prevent personal injury from tire blowouts.

When inspecting tires, don't use sharp tools to knock on the tire, which can also easily trigger a blowout.
