At present, many luxury brands on the market use run-flat tires. On the one hand, this kind of tire has a relatively high safety factor compared with ordinary tires. On the other hand, it can save a certain amount of trunk space. But explosion-proof tires mean that you are not afraid of punctures? In the case of using explosion-proof tires, do you really not need a spare tire?

Explosion-proof is not non-explosive, the real role should be clear

I believe that many consumers will be misled by the word "explosion-proof", thinking that the tire will not burst. In fact, the full name of a run-flat tire is a run-flat tire, which is abbreviated as RSC in English. Generally, if the tire with the RSC logo printed on the sidewall of the tire is a run-flat tire.

Although many people habitually call run-flat tires as run-flat tires, this does not mean that run-flat tires will not burst at all. For this point, we must first clarify the role of run-flat tires, which is to ensure that the vehicle can still travel at a lower speed for a certain distance with thick sidewalls and internal structural support when the tires are flat or flat. To put it simply, run-flat tires are not explosion-proof, just because the sidewalls are treated, the probability of explosion-proof is small. In the case of air leakage, air shortage or bulging, the tires still need to be replaced in time.

How to choose is the key, security awareness can not be less

Since the explosion-proof tire is not explosion-proof, then consumers still need to choose the explosion-proof tire? To answer this question, first look at a set of data. When the vehicle travels at a speed of more than 160 km/h and the front tire bursts, the mortality rate can reach 100. However, 46% of accidents on expressways are caused by tire failures, of which tire blowouts account for 70% of the total. In other words, although there is still a certain chance of tire blowout, compared with ordinary tires, run-out tires can improve driving safety to a certain extent.

At the same time, the spare tire saved after using the anti-blowout tire can further optimize the front-to-rear weight ratio of the car body and increase the storage space at the same time. Therefore, it is not difficult to understand that many luxury brands make puncture-proof tires standard. Since it is said that there are so many benefits of flat-proof tires, should vehicles blindly pursue standard flat-proof tires? This is not true, excessive superstition of flat-proof tires is not desirable. Consumers should develop a good habit of checking tires regularly, pay attention to the service life and condition of tires, and develop a good safety awareness is the key point.

The cost is too high and uncomfortable, and traditional tires are also practical

In addition, the tire is not all advantages. In particular, the thicker tire wall makes the tire hard, which is not conducive to the later tire repair. Secondly, subject to the cost, the price of many run-flat tires is not cheap. Therefore, at present, only many luxury brands will come standard, and entry-level family cars are only equipped with ordinary tires.

At the same time, the use of run-flat tires also has certain requirements for the adjustment of car suspension. Thicker sidewalls have worse shock resistance and reduced comfort than traditional tires. At the same time, some hard impacts brought by the road will be directly suspended. bear. If ordinary family cars want to replace run-flat tires, the suspension must be readjusted to ensure safety.
