In the process of driving a trailer, safety issues have always been issues that we must pay attention to. Among the many safety issues is the puncture. Especially in the high temperatures in summer, according to statistics, about 1/3 of traffic accidents on the highway are caused by tire failure. How to avoid these problems, we must first understand the reasons for the puncture under the trailer, according to the station. The following are the main reasons summarized by experience. Everyone can refer to the following:

● When the actual culprit weight of the culprit trailer with overloaded high-pressure inflatable puncture tire 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 the tire to leak. Gas, if there is a tire leak in the rear double-wheel bearing capacity and the driver fails to find it in time, it will cause the other tire in the rear two wheels to be overloaded and punctured.
Overloaded trailer

● High temperature leads to tire pressure The tire temperature rise makes it easier to cause the brake drum to gradually generate high temperatures after the tire is used for a long time. Because the truck tire valve is close to the middle position of the inside of the tire rim, it is close to the brake drum and the brake drum produces The high temperature causes the rubber at the bottom of the valve to expand and deteriorate, and the sealing performance deteriorates. Trucks that often travel in mountain areas and hilly regions often have to use brakes for a long time. Therefore, tire valves are generally poorly sealed, and therefore the probability of puncture is higher. .

● Safety tires should be used with caution without injury
Damaged tire

An internal injury to the tire means that the tire inner chamber was once repaired by a sharp hole or a valve leak. Repaired tires have far less tightness and load capacity than unrepaired tires. The repaired parts of the inner tires of the repaired tires are generally covered with rubber gaskets. The purpose of these gaskets is to repair the tires and to prevent the repaired tires from being “wrapped” at the tire's perforation. However, the gasket that protrudes from the inner surface of the tire has wear-resistance to the repair of the inner tube under load. If the gasket is frequently overloaded or bumpy, it is easy to make the tire puncture.

● cold water cooling is not desirable hot, cold, explosive tires Most of the trucks are equipped with a watering system, it is recommended that card members in the departure of the pressure of water to open the tires to cool, do not wait until the tire temperature rise and then open the water Cooling, if the temperature is too high when the use of cooling water, then the outside temperature of the tire caused by rubber shrinkage, while the tires still maintain a higher temperature and pressure, resulting in different tires inside and outside the force, it is very easy to cause puncture and brake Ruptured pan.

● Damaged tires should be replaced in time to avoid friction and heat caused by fire after the double bridge models and semi-trailer models due to a large number of tires, puncture is not easy to find, continue to drive after the broken tires will rub with the intact tire heat Until another tire also punctured. After a twin tire bursts, the hub will come in contact with the ground to generate a lot of friction and then ignite the damaged tire.
