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?
(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.
Second, why do some businesses recommend using out-of-air guaranteed tires?
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.
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.
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.
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.
