Hello everyone, this is a column focusing on car repair and maintenance. There are car mysteries you don’t know, and it will teach you how to avoid the big pits on the road of car ownership. I believe that not only you but also many people have a certain sense of obscurity about the car aftermarket, which will help you uncover the unknown stories of car repair and maintenance.
It has been more than one hundred years since the car was born. With the blessing of various technologies, the car can have more powerful functions. Now many models are gradually using explosion-proof tires to replace the traditional tires.
When changing tires, many car owners are recommended by the store to replace blowout-proof tires, but is it really necessary to do so?
In this issue, the editor will take you to interpret: to prevent a flat tire, is it necessary to upgrade in the end!
What is a flat tire?
Explosion-proof tire is a folk word invented by the people, and its real name is air-deficient tire.
(below, all air-deficient tyres are used instead of blowout-proof tyres.)
In other words, after running out of air, the tire can remain in its original state and continue to drive a distance without collapsing instantly like a traditional tire. The out-of-air guaranteed tire is a different kind of tire, which has a unique identity on the side of the tire.
The biggest difference in the structure between the air-deficient tire and the traditional tire is that the tire wall is particularly thick, even if there is no air pressure inside the tire, it can still maintain close to the original state by virtue of the thick tire wall and provide some support for the car. Therefore, in general, models equipped with out-of-air guaranteed tires cancel the spare tire, because it is not needed at all.
The out-of-air guaranteed tire will be very hard compared with the traditional tire, so it is very difficult to replace. In the later maintenance hours, it will also be higher.
Second, why do some businesses recommend using out-of-air guaranteed tires?
Tires are daily consumables, and the frequency of replacement is relatively high. When you change tires, some black-hearted merchants will take the initiative to recommend air-deficient guaranteed tires to you, introducing that they have a long service life, super wear resistance and, above all, never burst.
The main reason why black-hearted merchants are so active in recommending air-deficient guaranteed tyres to you is that they are too expensive.
At present, out-of-air guaranteed tires are only available in some high-end models, and the price of a single tire is usually more than three times higher than that of ordinary tires. For businesses, this is the best way to improve GDP.
Are three air-deficient guaranteed tires (explosion-proof tires) really explosion-proof?
According to the above data, the most important feature of the air-deficient tire is that the tire wall is thick enough to maintain the original supporting force under the condition of lack of air.
However, this does not mean that it has the ability to prevent a flat tire.
Even if the fetal wall is thick enough, it still can’t stop the cracks. Cracks in the tire wall are very dangerous. when the car is driving, the tire load increases gradually, and this position is likely to be torn open.
The air-deficient guaranteed tire is made of the same material as the ordinary tire, which will still be aging and chapped.
Many people think that they can ignore any road conditions after installing a gas-deficient tire, and often use their courage to challenge all kinds of kerbs.
The material itself has a physical property, and the higher its hardness, the worse its toughness. The hard wall of the explosion-proof tire is actually very brittle, and when the force exceeds its hardness limit, its wall will crack directly, which is very rough.
Like this in the picture, the tire wall burst a slender hole, really maintained the belief that it would rather break than bend, the whole tire will directly collapse and can no longer support the wheel.
On the other hand, ordinary tires are more flexible and will bulge a big bag first, but they will not burst as directly as the tire that runs out of air. Of course, it will also be more vulnerable, and the slightest bump can lead to bulging of its fetal wall.
See here, you also know some of the characteristics of air-deficient guaranteed tire, it is not as magical as the legend, the disadvantages of traditional tires, it still exists.
Four: is it true that there is no advantage in air-deficient guaranteed tyres?
The emergence of gas-deficient tyres is the result of the progress of the automobile industry, but also condenses the sweat of a large number of researchers. The function of driving under zero tire pressure appears, and the spare tire can be cancelled directly. The space in the car can be further saved, and it will be better for users in terms of space experience.
Which models are more suitable for the use of gas-deficient guaranteed tires?
If the original factory is equipped with air-deficient guaranteed tire model, can only use out-of-air guaranteed tire.
If the original factory is not a car that runs out of air and guaranteed tires, you should be careful when upgrading air-tight guaranteed tires. Because the tires are adjusted with the whole vehicle, changing the properties of the tires may cause the vehicle to lose its original maneuverability. The original car is equipped with spare tires, so the significance of replacing air-deficient guaranteed tires is not obvious.
The advantages of any product should not be deified, if it is really so powerful, the manufacturer has long been vigorously promoted, where the turn to get the merchant to recommend it to you. Both the repair shop and the merchant are actually selling anxiety, and once they are anxious, they are bound to be cut off leeks. It’s not easy to keep a car, and car owners really need to learn more, otherwise they will really become leeks.
