The tire is an important part to ensure the normal operation of our vehicle, and it is also the only part of the car that contacts the ground. With the development of tire technology, nowadays passenger car tires are basically in the form of tubeless tires, which also brings the risk of puncture. Imagine how dangerous it is if a car punctures a tire at high speed.

There are many problems that cause punctures, most of which are caused by external force damage. Excluding external forces, I believe that most people believe that high tire pressure is the most likely cause of puncture, but I want to say that low tire pressure is more Do you believe it is easy to blow a tire?"

Only high tire pressure can cause a puncture?

It’s not unfounded that a puncture caused by high tire pressure is not unfounded. Once the tire exceeds the standard tire pressure, the impact resistance of the inner ply will decrease. In the case of high temperature and high speed, high tire pressure tires do have a high possibility of puncture. However, many people deliberately increase the tire pressure in order to improve fuel economy. This is a very wrong approach.

In addition to tire pressure, tire temperature is also an important factor affecting tire safety. When the outdoor temperature is beyond our control, we must try our best to control the temperature of the tires not to heat up quickly. Therefore, when parking, especially in summer, avoid parking in places where the sun is unobstructed. If it is really helpless, we must Find a non-black ground to park. Black heat absorption is a common sense of physics that everyone knows, and it will also conduct heat to the wheels.

Except for artificially increasing the tire pressure deliberately, most repair shops or 4S shops will not charge your tire pressure to exceed the standard. This is not worth the gain, and it is also familiar to a repairer. Therefore, high tire pressure is rare in our daily car maintenance.

In fact, low tire pressure is more likely to cause a puncture

On the contrary, there are many riders who do not develop the habit of checking the tire pressure frequently. The habit of walking in the car makes them ignorant of the four tire pressure. Therefore, low tire pressure conditions are more common. Even some car owners do not reinflate the tires for several months, and the tire pressure of individual tires has dropped to 2rap. This will greatly affect your tire life.

Once the tire pressure is lower than 2rap, the contact area between the tire and the ground will increase due to the weight of the vehicle. In addition to increasing the friction, increasing the tire temperature will also increase. The curvature of the sidewall bulging outward is also larger. Has destroyed the healthy stress points of tire operation. This is an important reason why low tire pressure can easily cause a puncture.

What part of the tire will be damaged by low tire pressure?

For our current radial tire, after dissecting the tire, we can see that there are many layers inside. Among them, the high temperature resistance of the nylon belt layer and the cord layer is not good. Once your use temperature exceeds the expected set value, it will cause breakage, etc. In extreme cases, the local force will be uneven, and the tire will burst. phenomenon.

Low tire pressure, if it occurs on the front wheels, will cause heavy direction and deviation from driving. Our driver can still detect it. But if it is in the rear wheel, it is not so easy to find. This is also the terrible consequence of irregular tire pressure checking.

Where is the standard for tire pressure reference?

For the standard tire pressure, in fact, every car is different. Each car must formulate a standard tire pressure according to the body weight and tire model. In reality, the tire pressure formula of front wheel 2.3 and rear wheel 2.5 is often talked about by us. We must correct these incorrect perceptions. If you want to find the tire pressure standard that meets your vehicle, just open the fuel tank cap and you can see the factory-set standard tire pressure value, isn't it very simple!

For long-term low tire pressure driving, the tire temperature will be higher, which will cause the early aging of the tire rubber. You can see that there are small cracks at the bottom of the tread pattern in the picture.

Low tire pressure failure phenomenon

And if the tire pressure of a certain car is lower than 1.5rap, it is very likely that the tires will squash when the weight is loaded and bumped. The flattened tire will be sandwiched between the ground and the wheel hub. Under the squeeze of hard objects, the side of the tire will experience serious wear. This kind of problem is common after a tyre puncture, we did not find out the first time. It is possible that during driving, the tire pressure drops sharply, causing wear.

Low tire pressure will also increase the contact surface between the tire and the ground. Affected by gravity, the edges on both sides of the tire will experience accelerated wear. This is something we can't handle with four-wheel alignment.

In the case of low tire pressure, the supporting capacity of the tire will also be reduced. When driving to the roadbed or bumps, it will also cause the tire side ply to break. The tire side drum is like this.

In the cognition of most people, high tire pressure is the culprit of a flat tire. It is undeniable that the impact of high tire pressure is indeed great. But in everyday cars, we do not deliberately increase the tire pressure, so high tire pressure is rare, but low tire pressure is often overlooked by us.

It is because of negligence that the tires run flat for a long time. Unconsciously, we have reduced the life of tires, and even brought hidden dangers that affect safety. Therefore, as a qualified car owner, it is necessary to develop a good habit of checking the tire pressure regularly and avoid using a car with low tire pressure. We have to check the four tire pressures every time before getting on the car, and refill in time when the tire pressure is low.
