After the weather turns cold and the temperature drops, does it have a big impact on tire pressure?

When the temperature is high in summer, experienced car owners will adjust the tire pressure to a suitable value, because too high tire pressure will affect the daily driving comfort and accelerate tire wear, while too high tire pressure will increase the chance of tire puncture when driving at high speed, so it is very important to check the tire pressure according to the local environment! The weather has turned cold recently, and I believe many cars have started to report tire pressure. Why? It's actually quite simple. Tire pressure will vary according to the ambient temperature. Today we will talk about how to adjust the tire pressure in autumn. I believe many riders are skeptical. Does the tire pressure need to be checked regularly? Just hit the tire pressure to a certain value, otherwise the tire pressure sensor will not give an alarm. In fact, this view is very common, and it cannot be said that there is a problem! It can only be said that too high or too low tire pressure will have a certain impact on car comfort and fuel consumption. For example, too high tire pressure has an impact on bumpy road driving, too high tire pressure will aggravate tire wear, and too low tire pressure will increase fuel consumption. Then the question is coming, how to adjust the standard tire pressure? The tire pressure of ordinary cars is not that complicated. Generally, the tire pressure values before and after are the same, most of which are 2.5bar, but for a medium-sized car or a car with different tire sizes, the tire pressure values before and after need different values. Different car models have different tire models, so the tire pressure is uneven. If you want to know the recommended tire pressure of your car, I suggest you refer to the owner's manual, the label next to the cab door, the drawer next to the driver's seat and the standard tire pressure gauge on the back of the fuel tank cover. It has the standard tire pressure recommended by the manufacturer, and the practical standard tire pressure value can give full play to the maximum efficiency of this car. Does it need to adjust the tire pressure when the weather is cold? This situation depends on the situation. If you run long-distance buses all the year round, the tire pressure can be 0.2bar higher than the recommended value. If you only travel in urban areas, it is recommended not to increase or decrease the tire pressure. The tire pressure value of some off-road vehicles needs to be adjusted according to climate change, for example, it needs to be adjusted to 2.7/3.0bar in winter and slightly reduced in summer; There is also to adjust the tire pressure according to the vehicle load, such as full load 3.0bar and half load 2.5bar! Therefore, after the temperature drops, you only need to press the standard, and you don't need to increase the tire pressure. It needs to be added that automobile tires will be tested at low temperature, so the tire pressure is measured by scientific methods. How to get a very standard tire pressure, the owner needs to prepare a tire pressure gauge, because the tire pressure is greatly affected by temperature, and the tire pressure after hot tire is about 0.5bar higher than that after cold tire, so the tire pressure is tested before the tire is hot before departure, and the tire pressure is the most standard at this time.
