The proper tire pressure

2020/11/10

Car owners usually pay special attention to regular maintenance of their cars. It is very common to wash your car and wax it. Some car owners pay special attention to the maintenance of tires. After all, when we drive on the road, tires are the most important thing. You can’t drive without wheels. Therefore, before driving out, we will check the tires to see if they are worn seriously, if there is any air leakage and blistering, and if the tire pressure is abnormal. Many novice car owners don't know much about tire pressure, so they ask, what is the appropriate tire pressure? In fact, many car owners are wrong, and people who know cars do the same.


Many people who don't know the tire pressure inflate their cars. Generally, they just let the repairman watch the inflation. If the repairman is unfamiliar with your car, he will be charged at the usual rate of 2.5. The standard tire pressure is between 2.2 and 2.5, and there are very few cars with the tire pressure just 2.5. Therefore, if the tire pressure is too low, the braking distance will be shortened, and the car will consume a lot of fuel. But there is another advantage: the car will have better grip when turning. If the tire pressure is too high, the wheel friction will decrease and the fuel consumption will also decrease. But the problem is that when the friction decreases, the braking friction will decrease, and accidents will easily occur during braking. Moreover, if the tire pressure is too high and serious, it will lead to tire blowout. If it happens on the road, it's dangerous.


People who know cars say that the tire pressure in different seasons should be adjusted reasonably according to the vehicles and road conditions. We all know that the temperature is very high in summer and very cold in winter. According to the principle of expansion with heat and contraction with cold, when the tire temperature rises and the tire pressure rises in summer, the tire pressure should decrease by 0.1 ~ 0.2 points. In winter, contrary to summer, the tire pressure should be increased by 0.1-0.2 points.


Most car owners don't know that their cars have a clear tire pressure standard, which is the most suitable tire pressure standard for their cars. After all, the condition of each car is completely different, so the tire pressure is different. But you must keep your tires intact when driving on the road. At this time, proper tire pressure is very important.
