How normal is the front and rear tire pressure adjustment?

What is the normal tire pressure around summer? The tire pressure should be adjusted between 2.3 and 2.5 (the corresponding reference range is about 230-250). Please refer to the detailed requirements in your vehicle manual for details. There are also detailed tire pressure tips and requirements on the inside of the fuel tank cover of your vehicle. Proper tire pressure can better ensure the overall driving control and comfort of your vehicle, and at the same time, it can effectively extend the service life of tires. Usually, you can pay more attention to self-inspection and adjust the tire pressure in time if it is abnormal. It is normal for the cold tire pressure to be between 2.2 and 2.5. The generally recommended cold tire pressure is 2.5, so the fuel consumption will be lower, and the tire pressure can be controlled within the safe tire pressure range of 3.0 when driving at high speed. In fact, different models have different tire pressure requirements, and the maximum and minimum restrictions on tire pressure are also different. The requirements for installing the same tire on different models are different. Therefore, the best tire pressure is not a fixed value, depending on different models. The standard tire pressure value of each vehicle type is marked in the user manual of the vehicle or the inside of the fuel tank cover and the co-pilot position under the B-pillar of the vehicle. Although the manufacturer gives the best tire pressure value, it will change with the change of temperature. It is hot in summer, so it is suggested to reduce the tire pressure by 0. 1~0.2, and increase it by 0.2 in winter. There are subtle differences in tire pressure between different models and vehicles, which can be found in the side of the fuel tank cover or cab door and in the user manual, and it is also the most accurate. Other factors that need to be referred to for proper automobile tire pressure: 1, winter: according to the standard tire pressure principle, it should be increased by about 0.2bar, and summer: when the automobile is parked in the open air, the air pressure can generally be lower than the standard 0. 1bar to avoid high-temperature tire puncture. 2. No-load/half-load: according to the lower limit of automobile tire pressure standard (the tire pressure on the vehicle label sticker can be used as the minimum tire pressure reference value). Full load: the upper limit of full load according to the automobile tire pressure standard (the maximum tire pressure value on the tire label can be used as a reference for the theoretical maximum tire pressure). Within the normal range, there is not much problem, the only difference is that there is a little difference between fuel consumption and comfort. And these differences may not be easily detected because they are relatively small. Visually inspect more on weekdays, subject to the actual measurement of cold tires. Let's discuss the air pressure in your manual first. When the front wheel is lightly loaded and the air pressure is about 2.2, you will see that the tire deflates too much in the cold state. Personally, the original intention of the manufacturer is to drive on a flat road to improve the comfort and make up for the lack of chassis design, but at the expense of the service life and energy saving of tires. Driving on the characteristic roads of China with frequent tire bursts, full manhole covers and full speed bumps can easily cause tire bulging or even direct tire bursts. This air pressure is unrealistic. It is suggested that all new tires within 30,000 kilometers should be filled with nitrogen. 2.4-2.5 before winter. After winter, it's 2.5. If it is often fully loaded, it is recommended to 2.6. Because heat expands and contracts, a little lower air pressure in winter will improve the adhesion between rigid tires and the ground, which is helpful for braking and handling. There is no ice on the pure snow trail, which can increase the tire pressure, but
