How much should the tire pressure hit
What we call "tire pressure" is actually tire pressure. The index of this pressure indicates the state of tire inflation. When every car leaves the factory, the manufacturer will provide a recommended tire pressure value for the owner. The tire pressure index is usually posted on the inside of the B-pillar (behind the front door), and if it is not posted here, it is usually recorded on the fuel tank cover or the vehicle's manual.
Don't underestimate the recommended tire pressure, which is actually the most suitable value for this set of tires. Exceeding or not exceeding this value will have a certain impact on the vehicle. Too high tire pressure value will make the tire become drum shape. After deformation, it can be imagined that the ground area of the tire will be reduced, so the adhesion of the tire will also be reduced. In addition, as the tire is constantly rubbing against the ground, heat will be generated after driving, and heat accumulation will make the tire pressure rise. If the tire pressure is too high, which is higher than the maximum tire pressure, it is more likely to have a tire blowout when encountering road impact, which can be said to be a major safety hazard. But this situation is more prominent in summer and high-speed driving, so we should pay attention to the tire pressure in summer, and never hit the tire pressure too high. Since too high air pressure can lead to tire blowout, it's OK to reduce the tire pressure? Reducing tire pressure is OK, but too low tire pressure is definitely not a good thing. If the tire pressure is too low, the tire will shrink, the grounding area will increase, and the rolling resistance will be greater, so the fuel consumption of the vehicle will increase accordingly. In addition, tire rolling is a process of continuous cyclic deformation. Some studies have shown that, driving under low tire pressure for a long time, due to the large amount of tire deformation, the tire's gum aging speed will increase, and its life will be reduced by 10%. When the tire's gum aging, it is easy to produce tire blowout. Therefore, keep the tire pressure at a proper value, especially for the car owners who often run at high speed.
At present, many original models are equipped with tire pressure monitoring function as standard. When the tire pressure is abnormal, the lamp will light up to give an alarm, but not every car has a specific tire pressure value, so it is necessary to check the tire pressure. There are many kinds of tire pressure gauges on the market. In fact, there are tire pressure gauges on the air pump that you give away when you buy insurance or other auto products. However, it is better to confirm the accuracy of the values before using them.
Generally, you don't need to buy this kind of professional tire pressure gauge, but if you often use it, you can still consider buying one yourself, which is convenient and inexpensive.
Insurance companies usually give away pump for vehicles. The efficiency of pump is usually not high, but it can be used in emergency or as tire pressure gauge.
Once and for all, the way is to install tire pressure monitoring. There are many brands and styles that can be selected in the market, and the functions are also very rich. The key is to be able to understand the current working status of tires in real time.
A car is not a disposable consumer product. When you buy a car, you have a relationship with it. In the future, you need to take care of the maintenance, service and even repair. Of course, many things can be paid for by others, but there are also many things that are good for the car or yourself if you know, know and even participate in. The car is very simple. If you treat it well, it will definitely repay you.
