Tires are very important for flatbed trailers. Once a tire burst occurs, it will be a very dangerous job. Therefore, we must understand the causes of flat car tire burst. Only by knowing the causes of tire burst can we better prevent it.
1、 Causes of flat trailer tire burst
1. High temperature
High temperature is the main cause of flat trailer tire burst. Due to the high temperature climate in summer, the road temperature continues to rise. Once the road temperature rises, the tire surface temperature is very hot due to the friction between the tire and the road. Under the thermal expansion and cold contraction, the tire carcass expands and thins. In addition, the tire is constantly heating during the process, so it simply leads to tire burst.
In China, the situation of trailer overload operation is widespread. It can be said that no flat trailer does not overload. Overload is also one of the main causes of flat trailer tire burst. High pressure tires are widely used in freight flat trailers produced and used in China, and double tires are generally used for rear wheels with large bearing capacity. Under normal circumstances, when the load on the wheels is the maximum allowable value, the internal pressure of high pressure tires is 5-7 atmospheres, When the actual load capacity of the freight flat trailer exceeds the maximum allowable load of the wheel, the internal pressure of the tire will increase. When the internal pressure of the tire exceeds the sealing pressure of the tire valve, it will cause tire air leakage. If one tire in the rear two wheels with large bearing capacity leaks and the driver fails to find it in time, it will lead to excessive load and tire burst of the other tire in the rear two wheels.
Special trailer manufacturers talk about the possibility of flat trailer tire burst if speeding for a long time. Due to excessive overspeed for a long time, a lot of heat will occur when the tire rubs violently with the ground. The heat accumulation to a certain extent will lead to the high temperature of the tire itself, which will lead to the rapid rise of tire temperature, and then lead to the rapid aging of rubber and tire burst.
4. Abnormal tire pressure
Abnormal tire pressure refers to the lack of tire pressure and too high tire pressure. An excessively high tire is like a balloon filled with too much gas. After being squeezed, it will simply form a tire burst, while a tire with too low tire pressure will cause the contact surface between the tire and the ground to become larger, and the friction resistance will also become larger when traveling. When the flat trailer travels at high speed, the tire will heat up quickly, which will make the tire hot, Then more simply lead to the discovery of a flat tire.
5. Excessive wear
If the tires of the flatbed trailer show excessive wear and are not replaced in time, it is very easy to have a tire burst. The load capacity and compressive strength of the excessively worn tires are now far lower than the normal tires, so it is difficult to maintain the normal travel of the flatbed trailer. In addition, the factors such as high temperature, overspeed and road fluctuation are very simple to have a tire burst.
6. Tire air leakage
The flat trailer tire is punctured by nails or other sharp objects, but the tire is not punctured temporarily. The tire will show air leakage, and we have not found it in time. If it is used normally, it may cause tire burst.
2、 How to prevent a flat tire
1. Check tire pressure regularly
Maybe we know that the change of tire pressure is related to the change of temperature. Generally speaking, in colder climates, cars simply show a flat tire. Therefore, we should pay special attention in autumn and winter. We should pay special attention to check the tire pressure of flat trailer. If the tire pressure is insufficient, it may lead to tire burst. It should also be noted that the probability of tire burst is greater when the tire is out of air. If it is found that the tire continues to move when the tire is out of air, the inner side of the tire will be deformed. After driving for a long time, a lot of heat will accumulate on the inner side of the tire, which will lead to the change of internal pressure of the tire and cause tire burst. Therefore, when we find that the tire is short of air, we must have enough air to exercise.
2. Pay attention to the application environment of tires
Flat trailer tires are rubber products. Therefore, when traveling, parking and storing tires, pay attention to touching with oily, acidic, hydrocarbon and other chemicals, and advocate parking the vehicle in a cool place to prevent premature aging of tires.
3. Replace the aged tires in time
Some people may think that as long as the tire is not old, it can be used continuously. In fact, this is not the case. The tire has service life. If the tire is used continuously, it may have a tire burst. Under normal circumstances, the service life of tires is 2-3 years or about 60000 kilometers. Tires that exceed the service life or are seriously worn should be replaced in time. Therefore, we should pay close attention to the tire condition of our car and replace new tires in time in case of problems.
4. Put the trailer in a cool position
In the scorching summer, if you need to park the vehicle for a long time, it is best to park the vehicle in a cool place to avoid the exposure of the tire in the scorching sun.
5. Do not overload
Sometimes we may have overloaded demand for many reasons, which is actually bad for the tires. When the tire is overloaded, the pressure of the tire increases, which is relatively simple, and the deformation increases due to compression. In order to bear such a large pressure, the internal pressure of the tire will also be added. At the same time, due to the addition of touch area, it will also increase the wear of wheel shoulder, especially the tire burst is relatively simple when going uphill. So we'd better not overload in driving.
6. Do not use worn tires
Because the road the driver usually travels on is more complex, it is difficult to prevent tire puncture. If there is a significant gap in the tire and it continues to travel, the tire burst may appear within a few kilometers. Therefore, we should form the habit of checking the tire in time to see if there are nails, scratches and other phenomena on the tire surface. Once found, we should repair or change the tire immediately. If you find some stones in the tire pattern, you should also remove them in time.
7. Pay attention to the speed level and load capacity of the tire
Due to different rubber and structure, each flat trailer tire has different speed and load limits. When selecting tires, the driver should see the speed level mark and load capacity mark on the tires, and select tires higher than the maximum travel speed and load capacity of the vehicle to ensure driving safety.
