5 signs of dangerous tire wear on a car

It is very risky to save on tires not only when selecting them, but also during use. Some shortcomings of fresh tires or the level of wear of old ones can be compared with a slow-action bomb. It is noteworthy that some critical flaws are not detected in the process of driving, but at a certain moment they can be a reason for the occurrence of a major accident.

You should always keep in mind that rubber is a regular consumable, having its own limited resource. Often, due to excessive loads and large wear, it “dies” before the allotted time, and the more quickly you notice the signs of a deadly “disease”, the better.

Tire production

The most frequent event to which actively operated rubber is exposed is tread wear. In accordance with the rules of the road, its minimum height on summer tires of passenger cars must be at least 1.6 mm. It should be noted that initially this parameter is equal to 7.5 - 8.5 mm. In fresh winter tires, the tread depth ranges from 9 to 15 mm, and the minimum acceptable value is 4 mm.

Also it is necessary to take into account that tires are often subjected to uneven wear, because measuring the tread height is required along the entire length of the pattern, and this should be carried out by specialists using special tools. When your rubber has the above indicators less than the standard, then we recommend to get rid of it as soon as possible.

Naked cord

It should be noted that between the tire tread and its base there is a breaker, which consists of a multi-layer cord. When it becomes noticeable through the wear on the old tire, then this indicates the maximum level of rubber production, which means it's time to change it. In the fresh version, too, the cord from some kind of severe damage can appear. In both situations, the further use of the tire is very risky, because a defective breaker will cause deformation and slow separation of the entire tread.


Any damage to the base of the tire from the inside can cause a hernia. As a rule, it begins to form from the powerful blows of wheels on potholes, potholes and curbs. However, sometimes this happens because of an industrial marriage, under the action of which began the destruction of the frame. However, the presence of a hernia indicates a gradual transition of air from the inside to the tire carcass, which can always result in instantaneous tearing.


As a rule, such defects appear on the developed tires when driving through potholes and bumps. Even when they are small and not very deep - this is the first bell in order to replace the rubber. Under the influence of various circumstances, they gradually increase and reach the cord. As a result, rust acts on the belt layer and subsequent separation occurs. Therefore, each crack indicates the need for immediate tire replacement.

Production rate

More and more often, tire manufacturers equip their own products with a special wear indicator. He exists different species. Most often the conversation is about a small transverse planochka made of rubber, having a height of 1.5 mm and placed in the recess of the tread itself. After the tread depth goes one level with it, the tire should be changed immediately. In most cases, the presence of the indicator is marked on the side of the tire with the help of letters TWI, a sign in the form of a triangle or by means of a separate logo.
