Everyone said that the journey of a thousand miles begins with a single step. The normal driving of the car depends on the tires. For tires, in addition to their own quality problems, the impact of tire pressure on the tire is also critical, too high or too low will shorten the life of the tire. Many car owners often encounter sudden increase in fuel consumption during the use of the car, the steering wheel becomes very heavy, and the vehicle is deflected during driving. In fact, these are caused by insufficient tire pressure. The vehicle is driven by the tire on the ground, and the tire pressure is problematic. Directly affect driving safety, car owners must pay attention.
What is the car's standard tire pressure? How much is the tire pressure of a car tire?
The weight is different for different models, and the tire pressure standard is different. But in general, the standard tire pressure of household passenger cars is between 2.2 and 2.5 bar, which can be slightly higher and slightly lower but not too large. I believe that many of my friends don't know the specific tire pressure value of their car. At this time, you can flip the vehicle user manual.
The hazard of abnormal tire pressure:
Simply put, when the tire pressure is too low: the tire wear is intensified, the tire is prone to puncture, and the fuel consumption of the car is increased; when the tire pressure is too high: the tire grip is reduced and the wear is fast, the braking performance is weakened; when the four tire pressure is unbalanced : It is easy to run off when driving, and accelerate the life of tires with less tire pressure. It can be seen from the above that the abnormal tire pressure will not only reduce the life of the tire, but also seriously endanger the driving safety. According to statistics, 70% of the traffic accidents on China's highways are caused by punctures, and 75% of all the causes of punctures are caused by insufficient tire pressure.
Precautions for tire pressure measurement:
The tire pressure of cold tires and hot tires is not the same, especially when measuring. Under normal circumstances, the hot tire is about 0.2 bar higher than the cold tire pressure. The standard tire pressure we usually refer to on weekdays is the cold tire pressure. If the measured tire pressure is reduced by 0.2 bar, it is the obtained cold tire pressure.
Tire pressure should be adjusted according to the season:
According to different seasons, the tire pressure should be properly adjusted. The temperature difference between winter and summer will be expanded and contracted, and the winter tire pressure should be higher than summer. Generally, the winter is adjusted to 0.2 bar by the standard pressure of the car tire. In the summer, it is adjusted according to the standard lower limit of the car tires to prevent high temperature puncture.
Xiaobian suggestion: At present, many cars are not equipped with tire pressure monitoring system. It is recommended that drivers have their own tire pressure monitoring table. Regularly check the tire pressure on the tire to prevent the tire pressure from being too high or too low to accelerate tire wear and affect driving safety.
