【The owner's family car knowledge】In many people's impressions, the spare tire is an important configuration in the car, but now some vehicles are not equipped with a spare tire when they leave the factory. Once the tire is punctured, it needs to be repaired with the original tire repair fluid. For most car owners, tire repair fluid is a relatively unfamiliar gadget. When should it be used? How should it be used? I believe many friends are puzzled. Today we will introduce the precautions for using tire repair fluid.
● The role of tire sealant
Tire repair fluid is an emergency tire repair product. It is used when the tire is punctured and causes a loss of air, and there is no maintenance condition for the time being. The advantage is that it is simple and fast, no need to replace the spare tire, and no need to use a jack. The tire is automatically inflated while the tire is repaired, and then it can be driven to the repair shop normally.
At present, most models are still equipped with conventional spare tires. Only a few models have cancelled the

The advantage is that it is simple and fast, no need to replace the spare tire, and no need to use a jack. The tire is automatically inflated while the tire is repaired, and then it can be driven to the repair shop normally.
At present, most models are still equipped with conventional spare tires. Only a few models have cancelled the spare tire assembly due to space constraints (except for some models equipped with run-flat tires) and replaced them with tire repair fluid.
● Principle of Tire Sealant
Tire repair fluid is a synthetic polymer compound, in the form of a white foamy liquid. These tire repair fluids are stored in compressed air tanks, and when in use, they are injected into the tire through the valve. At the same time, the pressure of the compressed air tank is used to inject the liquid into the tire while inflating the tire. Afterwards, by driving, the tire repair fluid in the tire is evenly covered on the inner side of the tire under the action of centrifugal force, and a layer of sealing film is formed on the inner surface of the tire, which has the effect of repairing the tire.
● Types of tire repair fluids on the market/types of our experiments
On the Internet, there are many kinds of publicity about tire repair fluids. Through investigation, we found that there are two main mainstream tire repair fluids: one is ordinary bottled liquid. This product only has tire repair function and does not have automatic inflation function. It needs to be carried out with an air pump. Use, some models equipped with the original tire repair fluid will bring a small air pump; the other is the more common automatic inflating tire repair fluid, which claims to be able to achieve tire repair and inflation two-in-one without a jack or a tire without an air pump. The effect of this has become a product of interest to many car owners, and our experiments are also aimed at this type of product.
● How to use tire repair fluid
Putting aside those rhetoric propaganda, we have always been dubious about the effect of automatic tire repair fluid. Such a bottle of tire repair fluid can achieve such a magical tire repair effect? Let alone buy a few bottles, we simulate several common tire punctured conditions and introduce them to you with actual performance.
Situation 1: The tire is pierced / the nail is not pulled out / the tire is badly inflated
Imagine that when we were traveling by car, we found that the tires were flat. After getting out of the car for inspection, we found that the tires were punctured. There is no repair shop around, no one knows when the nails went in, and no one knows how long the remaining gas in the tires can last. At this time, I must be very disturbed...
We simulated this scenario and replaced a tire pierced by a nail on our test car. At this time, the nail was not pulled out and the tire was almost completely flat. Measure the tire pressure. At this time, the tire pressure is only 0.3bar. We started to repair and inflate the tire with the automatic tire repair fluid.
According to the instructions in the manual, first we need to hold the compressed gas tank in the hand and shake it quickly, about 1 minute. Then lift the outer tube and connect the interface with the tire valve. Tear off the ring of fixing ring next to the switch on the bottle body, place the switch in the "on" position, and the tire sealant will start to work automatically.
It can be seen from the transparent tube that the tire sealant will quickly fill the liquid in the compressed air tank into the tire, and the deflated tire will obviously start to inflate and rise. The whole process is very fast and can be observed with the naked eye.
