In the process of driving, if there is a problem with the tire, it will have a certain impact on driving safety. I believe that all drivers have encountered this situation. When driving, there will be some foreign matters suddenly stuck in the car. What should we do if the tire is punctured by a nail?
1. No air leakage when driving nails
In the process of driving, you should get off the vehicle in time to check if you hear the tire make abnormal noise. If you see that the tire is tied up by a nail, do not worry too much. First, use foam water to place the nail on the nail to see if there is any bubble. If there is a bubble, it indicates that the tire is leaking; if there is no bubble, it means there is no air leakage.
If there's no air leakage, it's OK. Can you keep driving?
When the car pierces a nail and there is no air leak, you should also go to the repair shop for inspection. Because the tires are all vacuum tires, even if there is no air leak at that time, there will be slow air leak after a long time. Even if there is no air leak, you should repair it in time. There is a potential safety hazard for the tires pierced with nails, and they are prone to blow out when driving at high speed. The owner must not pull out the nail on his own initiative. The correct way is to slowly drive the car to the nearby repair shop and take out the nail safely. If you don't take the nail and drive as usual, you may have potential safety hazards such as tire blowout when driving at high speed.
Of course, it's not something to deal with. The car should slow down and find a repair shop to repair it. Because the punctured tyre is a time bomb after all, especially when it suddenly bursts when running at high speed. Therefore, if there is no air leakage after driving the nail, it can not be pulled out temporarily, but it needs to be repaired in time.
2. There is air leakage when driving nails
① Fast air leakage
If we say that the tyre punctures the nail, we can also find that the tyre leaks faster, and we can't use this driving again. We can go to seek for help in situ. Because the tyre wall will also be damaged when driving under the condition of air loss, but the whole tyre can't be repaired, and the more serious is the potential safety hazard. In addition, if it is not convenient for rescue, it is also possible to change the spare wheel with the vehicle tools, and then drive on the road!
② Slow air leakage
If the tire leaks slowly, and the tire pressure of the car is sufficient, you can also drive to the repair shop at a low speed for maintenance, but you should also pay more attention to not driving at a high speed or driving for a long distance, because there is still a risk of tire blowout at this time, which will also harm your life!
Available methods of tyre repair:
1. Mushroom nail tyre repair:
Mushroom nail is the most advanced tire repair method at present. It needs to separate the tire from the wheel hub, and dynamic balance is also needed after tire repair. The difference between mushroom nail and patch tire repair method is that mushroom nail tire repair method can well fill the gap of the damaged hole to avoid the continuous expansion of the damaged part. The advantage is that it is safer and more stable than other methods. The disadvantage is that the price is slightly higher, the market price is generally more than 100 yuan, and it has certain requirements for the damaged parts, some irregular or large damaged parts are not suitable for mushroom nail repair.
2. Fire compensation:
The so-called fire repair is to apply the patch and then use the curing machine to do high temperature curing treatment, which can make the patch and the damaged part fit more firmly. However, this method is mostly applicable to the tires with thick tire wall, such as the tires of large trucks and passenger cars. Moreover, this method has higher technical requirements for repairmen, so it is not widely used in urban repair shops.
Tip: if the nail is found early after driving, do not pull out the nail. If you can stick to the repair station, you can stick to the repair station, which can save the matter of changing the spare tire. If it is found that the tyre leaks seriously, you must not drive forcibly, which is not only not good for the tyre, but also dangerous for driving. Listen to the old driver's words. If you insert them, don't pull them out!
