4 Dangerous Tire Types: Replace Immediately

Drivers, please pay attention! Data shows that almost 1 in 10 accidents on the highway is caused by a tire blowout. Especially in summer, when the temperature rises, tire blowouts are particularly likely to occur. Tires are like the "shoes" of a car. If the shoes are not good, you can't walk steadily, let alone drive safely. Today, the tire business will talk about which types of tires should never be used again to help everyone avoid dangers on the road.

Bulging tires: "Time bombs" with hidden dangers​

Bulging tires generally have their internal cord layer structure destroyed and their internal steel wires partially broken. This kind of damage often occurs when a vehicle passes through potholes and speed bumps at high speed, and the strong impact force instantly acts on the tire, causing the cord to break and the rubber layer to lose support and bulge outward.

Bulging tires must never be repaired. Some tire shops forcibly repair bulging tires for temporary benefits, which is nothing more than a self-deception and an extremely irresponsible practice to the car owner. The repaired bulging tires are a great safety hazard. During the driving process, the rubber at the bulge is under uneven pressure. 

As the speed increases and the road is bumpy, the pressure continues to accumulate, which may cause a tire blowout at any time. For example, on a highway, a car with a bulging tire suddenly burst at a speed of 100 kilometers per hour. The vehicle lost control instantly and hit the guardrail continuously, causing serious casualties and property losses. Therefore, once a bulging tire is found, it must be replaced immediately, and do not take chances. ​

Tires with treads lower than the wear mark: "Invisible Killer" of Wetland Driving​

Tires with treads lower than the wear mark are also called "bald tires". There are raised points in the drainage grooves of the tires to indicate the wear limit of tire replacement. Some car owners will replace the tires before the tires are worn to this point, which is a very wise approach. Because once the tires are worn to this point, they are basically almost "bald tires".

The tire pattern can not only increase the friction with the ground, but more importantly, it can play a role in drainage on rainy days. When the tire tread depth is insufficient, in rainy seasons, the tire cannot drain the water on the ground in time, and a layer of water film will form between the tire and the ground, causing the friction between the tire and the ground to drop sharply, resulting in slippage, the so-called "hydroplaning effect".

Imagine that while driving at high speed, the vehicle suddenly slips and loses control, the consequences are disastrous. According to statistics, the number of traffic accidents caused by "bald tires" in rainy days is much higher than that of normal tires, and its danger is self-evident. ​

Aging and cracked tires: "security loopholes" eroded by time​

In addition to bulging and excessive wear, tire aging is also a problem that cannot be ignored. Even if the vehicle has a low mileage, over time, the tire rubber will naturally age and small cracks will appear on the surface.

The normal service life of a tire is generally 3-5 years, which depends on the environment and frequency of use. Long-term exposure to sunlight, high temperature environment, or contact with corrosive substances will accelerate tire aging. 

After aging, the rubber of the tire becomes hard and brittle, and the elasticity and strength are greatly reduced. During driving, especially when encountering bumpy roads or sudden acceleration or braking, it is very easy to have accidents such as tread shedding and tire blowout. Some car owners think that the tires look usable, but they ignore that the internal structure has long become fragile due to aging. ​

Tires with severe trauma: "Fatal Injuries" that are difficult to repair​

Tires will inevitably suffer some trauma in daily use, such as being punctured by sharp objects and scraped against curbs. If the wound is small and located in the middle of the tire tread, it can continue to be used after professional repair under the condition of meeting safety standards.

However, if the wound is too large (more than 6 mm in diameter), located on the sidewall (the sidewall is the weakest part of the tire and is subject to greater deformation and stress), or the cord has been broken, such tires cannot be restored to their original strength and safety even if they are repaired. 

For example, if the sidewall of the tire is cut, it is like a cut in the human artery. Repair can only be a temporary solution, not a permanent solution. In subsequent use, the wound may crack again, leak air, or even cause a tire blowout at any time.​

Tires are the only part of the car that contacts the ground, and their performance is directly related to driving safety. For the safety of yourself and others, please check the condition of your tires regularly. Once you find any of the above tire conditions that are not recommended for use, be sure to replace them in time.

At the same time, in daily car use, you should also pay attention to correct driving habits, avoid sudden acceleration, sudden braking, and running over sharp objects, so that the tires always remain in good working condition.
