Why is it difficult to save a completely flat tire with a mini electric pump?
Tire clogs are a fairly common situation for car users. In many cases, when detected, the tire has completely evaporated. At this time, even using a twelve-volt mini electric pump to follow the car, the tire still cannot inflate.
The main reason is that when the tire is completely flattened, the tire edge may slip out of the wheel rim. Mini electric pumps with small capacity are usually only enough to pump tires that are not inflated, making it difficult to create pressure strong enough to press the tire edge tightly back to the rim.
When encountering this situation, drivers should carefully check the tire rims to determine if they are torn or not. If the tire rims are still intact, you can use a lever to lift the wheels to reduce the load on the tires. When the pressure is reduced, the mini electric pump will easily create more pressure and is likely to help the tires inflate.
In case a small puncture is found and there is an emergency tire patch available on the car, the driver can temporarily seal the puncture and then inflate it to move to the nearest repair facility. However, if the tear is large or the tire is heavily damaged, the safest solution is to replace the spare tire.
According to Mr. Jonathan Benson - tire tester of the automotive magazine Tyre Reviews (UK): "When the tire has completely flattened, continuing to try to pump with a low-power device is often not effective. It is important to restore the seal between the tire edge and the rim or replace the spare tire as soon as possible to ensure safety.
Should nails be removed from the tire immediately upon detection?
Many drivers have a habit of pulling nails as soon as they detect a sharp object on the tire. However, this is not always the right choice.
In fact, the nail stuck in the tire can temporarily act as a "stop button", helping air escape more slowly. If the nail is pulled out immediately, the hole will open and cause the tire to leak out faster.
In case the tire still has a certain pressure, the driver can leave the nail intact, pump in more air and move slowly to the nearest tire repair shop. However, drivers should not be subjective because when the car continues to roll, friction can cause the nail to protrude deeper, making the puncture gradually larger.
To limit risks, experts recommend equipping tire pressure monitoring systems to detect air loss early. In addition, drivers should bring fast tire patches and learn how to replace spare tires, because this is an important skill to help handle incidents when moving on the road.
