Tires are an important part of our vehicles and the only part of the car that comes into contact with the ground. With the development of tire technology, today's passenger car tires are basically in the form of vacuum tires, and with it also brings the risk of puncture. Imagine how dangerous it is for a vehicle to have a flat tire at high speed.
And there are many problems that cause punctures, the vast majority of which are caused by external force damage, and excluding external factors, I believe that the vast majority of people think that high tire pressure is the most likely cause of puncture, but I want to say that low tire pressure is easier to puncture Do you believe?
Only high tire pressure can cause a puncture?
It is not unfounded that a puncture is caused by high tire pressure. Once the tire exceeds the standard tire pressure, the impact resistance of the internal cord layer decreases. In the case of high temperature and high speed, high tire pressure tires do have a great possibility of puncture, but there are many people who deliberately increase the tire pressure in order to improve fuel economy, which is a very wrong approach.
In addition to the tire pressure factor, tire temperature is also an important factor affecting tire safety. In the case that we can't control the outdoor temperature, we have to try to control the temperature of the tires not to heat up quickly, so when we park, especially in the summer, avoid parking in the sun without shelter, if it is really helpless, we must also find a non-black ground to park. Black heat absorption is a common physics common sense that everyone knows, and it will also transfer heat to the wheels.
In addition to artificially deliberately raising the tire pressure, the vast majority of repair shops or 4S shops will not charge your tire pressure to exceed the standard, which is not worth the loss, but also a maintenance personnel is familiar with it. Therefore, high tire pressure is rare in our daily car maintenance.
In fact, low tire pressure is more likely to cause punctures
On the contrary, there are many riders who do not develop the habit of checking tire pressure frequently, and the habit of getting on the car and leaving makes them unaware of the four-tire pressure. Therefore, the working conditions of low tire pressure are more common. Some car owners even do not replenish their tires for several months, and the tire pressure of individual tires has dropped to 2rap. This will greatly affect the life of your tires.
Once the tire tire pressure is lower than 2rap, the contact area between the tire and the ground will increase due to the weight of the body. In addition to making it more frictional, it will also make the tire warmer. The curvature of the fetal side bulging outward is also greater. The healthy stress point that has destroyed the operation of the tire. This is an important reason why low tire pressure is easy to cause punctures.
What parts of the tire will the low tire pressure damage?
For our current radial tires, after dissecting the tires we can see that there are many layers distributed 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 fractures and other situations, and in extreme cases, the local force is uneven, and there will be a puncture phenomenon.
The case of low tire pressure, if it appears on the front wheel, will cause heavy direction and driving deviation. We drivers can still detect it. But if it's in the rear, it's not so easy to spot. This is also a terrible consequence of checking tire pressure from time to time.
Where exactly is the standard of tire pressure referenced?
For the standard tire pressure, in fact, every car is different. Each car must be based on the weight of the body, tire model to determine the standard tire pressure. In reality, the tire pressure formula of 2.3 in the front wheel and 2.5 in the rear wheel is often hung up by us. These are incorrect perceptions that we must correct. If you want to find a tire pressure standard that meets your vehicle's, you can directly open the fuel tank cover to see the factory-set standard tire pressure value, is it not very simple!
For long-term low tire pressure driving, the tire temperature will be higher, resulting in the early aging of tire rubber. You can see a small crack at the bottom of the tire pattern in the picture.
Failure phenomena with low tire pressure
If the tire pressure of a car is lower than 1.5 rap, it is likely that the tire will be flattened during the load and bumps. The flattened tire will be sandwiched between the ground and the wheel hub, and under the squeeze of the hard object, the side of the tire will be severely worn. This kind of problem is common after the tire is punctured, and we did not find it in the first place. It is possible that during the driving process, the tire pressure drops sharply, causing wear.
Low tire pressure will also cause the contact surface of the tire to the ground to increase. Affected by gravity, accelerated wear occurs on the edges of the tires. This is something we can't handle by doing four-wheel positioning.
In the case of low tire pressure, it will also reduce the support capacity of the tire, and when driving to the subgrade or bump, it will also cause the tire side cord layer to break, and the tire side drum is also the stroke.
In the cognition of the vast majority of people, high tire pressure is the culprit of puncture, and it is undeniable that the impact of high tire pressure is indeed very large. However, in daily cars, we do not deliberately increase the tire pressure, so the situation of high tire pressure is rare, but the situation of low tire pressure is often ignored.
It is because of neglect that it will cause the phenomenon of long-term driving of tires, and in the unconscious, we have reduced the life of tires, and even brought hidden dangers affecting 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. Before each time we get on the bus, we have to check the pressure of the four tires and replenish the air in time in the case of low tire pressure.
