The causes and inspection methods of tyre leakage


I believe that many owners will encounter this situation: after filling the tire, it will become flat in a few days. This tire slowly running gas problem is really very worrying, tire is one of the important parts to ensure the safety of driving, if there is a problem, the owner of the car is not stable. Below are several reasons for dark leakage of tires and self-test methods!

Damage to the side and inner edge of the tire

Some car owners have a poor sense of position and often let the side of the tire rub against the curb, which will eventually wear out the side of the tire. The damage to the inner edge of the tire is caused by operational errors when disassembling and assembling the tire on the wheel hub. This situation generally occurs during the process of installing a new tire or repairing the tire. Damaged sides and inner edges of tires can cause hidden leaks and a high risk of tire blowouts.

Inspection method: The degree of damage to the side of the tire can be directly observed, and in severe cases, cracking and bulging may occur. As long as this situation is found, it is necessary to replace the tire with a new one as soon as possible to avoid accidents such as a tire blowout. Whether the inner edge of the tire is damaged or not requires dismantling the tire before inspection. Therefore, when dismantling the tire at the repair shop, the owner should carefully supervise the operation of the repairman.

Foreign matter stuck in the tire

Puncture is the most common tire injury. Foreign objects that can easily get into a tire include nails, screws, iron wire, glass fragments, etc. Among these foreign bodies, nails and screws are most likely to puncture the tire, causing dark leakage of the tire, and will also be inserted in the tire damage, if not cleaned up in time, it may aggravate the damage degree of the tire damage.

Inspection method: Tire puncture foreign body, as long as we carefully observe the tire surface can be found. If the part of the foreign body is hidden, we can also sprinkle water on the surface of the tire, find the place where there are bubbles, and sometimes even hear the "hissing" sound of frustration.

Hub flange deformation

After the car tire is filled with air, the outer edge of the tire will tightly adhere to the hub flange to prevent gas leakage inside the tire. If the hub flange is deformed due to collision, it will affect its fit with the outer edge of the tire, causing hidden leaks in the tire.

Inspection method: If the hub flange is severely deformed, we can detect it with the naked eye; If the deformation of the wheel hub flange is not obvious, the wheel needs to be removed first, and then water should be sprayed on the connection between the tire and the wheel hub. The area where bubbles are generated is the area where the deformation of the wheel hub causes hidden leaks.

Hub rupture

Wheel hub breakage is rare. The rupture of the wheel will cause the gas inside the vacuum tire to leak from the crack, and the small crack will also become the hidden danger of the wheel fracture. It can be said that although this situation is rare, it is extremely dangerous.

Inspection method: The inspection needs to remove the wheel, and then see whether there are cracks on the surface and inner wall of the wheel hub. If the wheel is unfortunately cracked, quickly replace the new wheel.

Damaged tire valve

If no abnormalities are found on the tire, we can shift our attention to the valve. Most household cars are equipped with vacuum tires, with valves installed on the wheels, mostly made of rubber. After using the rubber material valve for a period of time, it will gradually age under the influence of sunlight, rain, and the pressure inside the tire, and the texture will gradually become hard, eventually cracking and leaking air.

Inspection method: Check the valve, in addition to checking for cracks on its surface, you can also touch the rubber of the valve with your hand to feel its softness. Since rubber valves are prone to aging and cracking, car owners may want to try replacing metal valves. Although the money spent on buying a metal valve can buy several rubber valves, a more durable metal valve will make people more confident and worry free.
