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.
If the tire is tied to a foreign object, you can find it by carefully looking at 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, or you can hear the sound of "squeaky".
If the door core is drenched with water and a bubble is found, it can be concluded that the valve core is leaking. At this time, we only need to loosen the dust cover, because it will tighten the valve core and cause air leakage. Happening.
In addition to the front of the tire being easily punctured by foreign objects, the side and inner edges of the tire may be damaged. Some car owners have a bad sense of position on the vehicle. They often rub the side of the tire against the road tooth when parking, once or twice, but the number of times will wear the side of the tire.
The degree of damage on the side of the tire can be directly observed. In severe cases, cracking and bulging will occur. If this is the case, it is necessary to replace the new tire as soon as possible to avoid accidents of puncture. It should be noted that after the tire side is damaged, it is not recommended to repair the tire. It is best to replace the new tire directly, because even if it is replenished, it is very easy to have a risk of puncture.
In addition to the side of the tire, the inner edge of the tire is also damaged. This is caused by mistakes in the operation of disassembling the tire on the wheel hub. This is mostly caused by the installation of new tires or the installation of tires after tire repair. Just reinstall it.
When the tire is full of gas, the outer edge will fit snugly against the hub flange to prevent gas leakage inside the tire. If the hub flange is impact-deformed, it will affect the fit to the outer edge of the tire, causing the tire to leak.
As with the side of the tire, the wheel flange is severely deformed. It can be seen with the naked eye. If the flange of the hub is not deformed obviously, the wheel can be removed, and then the water is sprinkled to the joint of the tire and the hub. The place where the bubble is generated is the dark leak. position.
Why put the hub rupture in the last item? Because this situation is very rare, the wheel rupture will cause the gas inside the vacuum tire to leak from the crack. Small cracks will also become a hidden danger of the hub break. Although rare, the risk is extremely high. If the above mentioned air leaks are not found, we need to inspect the hub. Before the inspection, the wheels need to be removed, 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.
