Nowadays, many car owners like to change their car to a set of tires with a lower flat ratio, which not only makes the vehicle more domineering and sporty, but also more beautiful. However, what you need to know is that it is not suitable to use low aspect ratio tires under any circumstances, otherwise it will not only make your tires easier to pack, increase the cost of car maintenance, but also easily increase the safety hazard of puncture.

10,000 km tires are bulging

Low profile ratio tires are easy to bulge

Recently, media reported that a car owner purchased a Mercedes-Benz with low aspect ratio tires (the tires are Pirelli), and the tires were bulged within 10,000 kilometers. After the tires were replaced, the bulge appeared again. The owner thinks that there is a problem with the quality of the tire, but according to the inspection of professionals, the tire bulge is caused by external force during the driving process of the car, which is not a quality problem.

Why are low aspect ratio tires more likely to bulge?

low aspect ratio tires

According to professional explanations, tires with a flat ratio of less than 45% are called "thin tires". Compared with "thick" tires with a high aspect ratio, thin tires are more likely to cause bulges.

Relatively speaking, the sidewall of a thin tire is much narrower than that of a thick tire, so the extension range will be smaller, the sidewall will be harder, and the tensile strength of the tire cord will more easily exceed its own limit. . Therefore, the thin tires are more easily damaged and bulged. That is to say, even if you drive normally, there will be a risk of bulging and puncture.

Do not blindly pursue low-flat tires due to "local" conditions

Low-profile tires are better for good pavement

In fact, for people who drive, we should choose tires with different functions according to the "local" conditions. Low-profile tires are more suitable for driving on highways with better pavement, so if the road has potholes, it is never a good thing for thin tires.

The use of tires should also be adapted to local conditions

If you go to the suburbs, or if the road is poorly paved, try not to use thin tires. You need to choose those tires with a higher flat ratio, or even some special tires. For ordinary car owners and users, multi-functional tires can actually cope with 90% of the road conditions. Do not blindly pursue tires with a low aspect ratio.

Without national standards and labels, there will be such misunderstandings

Why do so many people blindly pursue those tires that are not applicable? In fact, in the final analysis, the country still does not have a complete and comprehensive rubber tire standard, there is no tire product classification system, and there is no complete tire function evaluation system.

At present, only a "Green Tire Technical Specification" is used as a guide, which not only makes it impossible for enterprises to more accurately locate user needs, but also makes it impossible for consumers to better choose their own car tires. It also increases the difficulty for consumers to use, and even a consumption trap.
