What is the normal tire pressure?

Speaking of tire pressure, I believe everyone will be familiar with it, because when I was a child, I would be exposed to it when I stepped on a bicycle. Similarly, most automobile tires are pneumatic tires at present, but do you know how much air pressure should be added to the tires? And do you know what problems can be caused by too high or too low tire pressure? These questions are not profound knowledge, but they are questions that every driver must know and be clear about. Here is a brief explanation for everyone.

The "tire pressure" we are talking about is actually the tire pressure, and the index of this pressure indicates the state of tire inflation. When each car leaves the factory, the car factory will provide the owner with a suggested tire pressure value. This tire pressure indicator will generally be posted on the inside of the B-pillar (behind the front door) of the car. If it is not posted here, it will generally be recorded on the fuel tank cover or the car manual.

Don't underestimate the suggested tire pressure. This tire pressure value is actually the most suitable tire pressure value for this set of tires. If it exceeds or fails to reach this value, it will have a certain impact on the vehicle. Too high a tire pressure value will bulge the tire. After deformation, it is conceivable that the contact area of the tire will decrease, so the adhesion of the tire will also decrease. In addition, due to the constant friction between the tire and the ground, heat will be generated after driving, and the accumulation of heat will increase the pressure of the tire. If the tire pressure is too high, which is higher than the maximum air pressure of the tire, it is easy to puncture when encountering road impact, which can be said to be a great safety hazard. This situation is particularly prominent in summer and highway driving, so everyone should pay attention to the tire pressure in summer, and never press the tire pressure too high. Since the air pressure is too high, it will lead to a flat tire, so can we just lower the tire pressure? It is certainly possible to reduce the tire pressure, but it is definitely not a good thing that the tire pressure is too low. If the tire pressure is too low, the tire will deflate, and the contact area with the ground will increase, resulting in greater rolling resistance, thus increasing the fuel consumption of the vehicle. In addition, tire rolling is a continuous cyclic deformation process. The research shows that when driving with low tire pressure for a long time, due to the large tire deformation, the rubber aging speed of the tire will be accelerated and the service life will be reduced by 10%. When the rubber of the tire is aging, it is easy to puncture. Therefore, keep the tire pressure at an appropriate value, especially for car owners who often run at high speed.

At present, many models are equipped with tire pressure monitoring function as standard. When the tire pressure is abnormal, the alarm will light up, but not every car displays the specific tire pressure value. At this time, you need to check the tire pressure. There are many types of tire pressure gauges on the market. In fact, there is a tire pressure gauge on the air pump given when buying insurance or other automobile supplies, but it is best to confirm the accuracy of its value before using it.

Under normal circumstances, there is no need to buy this professional tire pressure gauge, but if you use it frequently, you can still consider buying one yourself, which is convenient and inexpensive.

Insurance companies usually provide air pumps for vehicles, which are usually inefficient, but they can be used in emergencies or as tire pressure gauges.

The solution once and for all is to install tire pressure monitoring. There are many brands and styles to choose from in the market, and their functions are also very rich. The key is to know the current working state of the tire in real time.

Cars are not disposable goods. After buying a car, I established a relationship with it and have to take care of it in the future. Of course, there are many things that others can do, but there are also many things that are good for the car and yourself if you know, understand and even participate. The car is simple. If you treat it well, it will surely repay you.
