Car tires are very important auto parts. Problems with car tires will lead to car breakdown. Car tires are also a problem with car tires. Car tires are very important auto parts. Problems with car tires will cause the car to malfunction. The dark leakage of automobile tires is also a manifestation of problems with automobile tires. Because the gas leakage is relatively slow, the owner of the vehicle generally ignores it. Later, after inspection, it was discovered that the tire was actually tied with a screw - let the tires leak If it is fixed, it will become a serious safety hazard sooner or later. The most direct is the direct scrapping of tires. In fact, there are several reasons for the dark leakage of automobile tires: â— Foreign matter is stuck into the tire. The foreign matter is the most common damage to the tire. Foreign objects that are easy to get into the tire include nails, screws, wire, glass fragments, sharp stones, tiles, and the like. Among these foreign objects, nails and screws are the easiest to pierce the tires, causing the tires to leak, and they are also inserted in the damaged parts of the tires. If they are not cleaned up in time, the damage of the damaged parts of the tires may be aggravated. Inspection method: When the tire is tied to a foreign object, we can find it by carefully observing the surface of the tire. If the foreign matter is hidden, we can also sprinkle water on the surface of the tire to find out where there is a bubble, and sometimes even hear the sound of "squeaky". â—The side and inner edge of the tire are damaged. In addition to the fact that the front of the tire is easily "concealed" by the hard object, the side and inner edge of the tire are also weak links. Some car owners have a poor sense of position. They often rub the side of the tire on the side of the tire. Over time, they will wear the side of the tire. The damage of the inner edge of the tire is caused by mistakes in the operation of disassembling the tire on the wheel hub. This situation basically occurs in the case. Replace the tires with new tires or tires. Damage to the sides and inner edges of the tires can cause tires to leak and have a high risk of puncture. Inspection method: The degree of damage on the side of the tire can be directly observed. In severe cases, cracks and bulges will occur. If this is the case, be sure to replace the new tire as soon as possible to avoid accidents. This kind of situation is generally not recommended to repair the tires, generally can directly change the tires, it is more important to compare the safety, if the puncture is not worth the loss. â— Tire valve damage If no abnormalities are found on the tires, then we can turn our attention to the valve. The family car is basically equipped with a vacuum tire, and the valve is mounted on the hub, and the material is mostly rubber. After using the rubber valve for a period of time, under the sun and rain and the air pressure inside the tire, it will slowly age, the texture will gradually become hard, and finally the crack will leak. Inspection method: Check the valve, in addition to seeing whether there is crack on the surface, you can also touch the valve rubber by hand to feel the softness. Since the rubber valve is prone to aging and rupture, the owner may wish to try to replace the metal valve. Although you can buy a few rubber valves with a metal valve, the more durable metal valve will make you feel more at ease and worry. â—Wheel flange deformation After the automobile tire is full of gas, the outer edge of the tire will closely fit with the hub flange to prevent gas leakage inside the tire. If the hub flange is impact-deformed, it will affect its tightness with the outer edge of the tire, causing the tire to leak. Inspection method: If the hub flange is severely deformed, we can find it with the naked eye; if the hub flange deformation is not obvious, it is necessary to remove the wheel first, then sprinkle water on the connection part between the tire and the hub, and the bubble is generated, that is, the hub deformation The area that caused the dark leak. â— Wheel rupture The reason for this dark leak is the last one because it is rare. When the hub is broken, the gas inside the vacuum tire will leak from the crack, and small cracks will become a hidden danger of the hub breaking. It can be said that although this situation is rare, it is extremely dangerous. It is generally a deflation caused by trachoma or small holes, which is quite dangerous if a break occurs. Inspection method: If you do not find the four reasons for the previous dark leak, then we have to check the wheel. The wheel needs to be removed before inspection and then the cracks on the surface and inner wall of the hub are observed. If the wheel is unfortunately cracked, don't expect it to be repaired. It is safe to replace the new wheel. Summary: The dark leakage of car tires is a very annoying problem, no car owners are willing to inflate the tires every other day. During the daily use of the car, the owner should always pay attention to the condition of the wheel. When there is a dark leak, it may be necessary to self-check the cause. After the repair shop, the drug can be repaired early, and the problem can be avoided by the unscrupulous store.
