Tire bulging

The problem of bulges in car tires is becoming increasingly common, but many car enthusiasts are at a loss when faced with bulges. So can the tire still be used if it's bulging? How to prevent tire bulges in daily life?

Do not use it again after 1 drum packaging

Tire bulging can be classified into many categories based on the direct cause, but regardless of the type of tire, it is actually caused by damage, and this damage is basically irreparable, even if repaired reluctantly, it cannot achieve the normal performance of the tire.

Taking the more common occurrence of sidewall bulging as an example, the direct cause of bulging is the breakage of the inner ply of the tire, which loses its supporting function. The tire is only separated by a layer of rubber inside and outside.

This layer of rubber is very weak, and if it is affected by other factors, such as excessive tire pressure, compression, high temperature, or punctured by sharp objects, it is easy to cause a tire blowout accident.

How to prevent tire bulging

1. Try to purchase tires with a larger flat ratio

It is mainly aimed at upgrading and modifying wheel hub tires in the later stage. When choosing tires, try to choose tires with a larger flat ratio, such as 225/45 R18 and 225/50 R18 tires. If you are not overly concerned about handling, it is recommended to choose a flat ratio of 50 to reduce the generation of tire bulges.

2. Develop the habit of regularly checking tires

Developing the habit of regularly checking tires can reduce the occurrence of bulging due to high or low tire pressure.

High or low tire pressure can affect the service life of tires. A study by Wuhan University of Automotive Technology has found that high or low tire pressure can easily cause a tire blowout. Every 20% lower than the standard tire pressure reduces the lifespan of the tire by 30%, and if the tire pressure is too high, it can lead to a smaller deformable range of the tire and make it more susceptible to mechanical damage.

3. Slow down on complex/pitted roads

Some roads inevitably have a lot of mud, broken bricks, or cement blocks, and many large and small potholes;

When driving on these roads, it is necessary to slow down the speed and reduce tire and ground impact, which can effectively protect the tires and avoid bulging.

4. Try to purchase the latest tires as much as possible

Tyres have a shelf life, so when replacing tires, we try to purchase tires that are as close to the current date as possible, artificially extending the service life of the purchased tires.

There is currently no unified statement on the lifespan of tires. The recommended service life for major automobile tire companies is 3-5 years, around 50000 to 100000 kilometers, and then it depends on the degree of wear and tear of the tires to see if they need to be replaced.

5. No pressure on the horse's teeth

When the vehicle rides on the shoulder, the tires are compressed, which can easily damage the internal structure and form bulges. During the daily driving process of car owners, they should try to avoid the behavior of pressing the horse's teeth as much as possible.

Most of the reasons for tire bulges are caused by humans, and avoiding tire bulges is actually very simple: just reduce unnecessary collisions during driving;

When it is inevitable to drive over obstacles, it is also necessary to ensure that the vehicle passes at a low speed and at a dull angle.

After the tire is bulging, it must never be used again and must be replaced. If it is not possible to replace it now, the driving speed must be reduced, and non flat roads must not be driven. If foreign objects or dents are encountered on the road at high speed, the probability of accidents will be very high.
