The tire pressure is all at 265. Is this normal?

In this weather, I measured the tire pressure at 265. Does it matter if the cold tire pressure is 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, the tire pressure requirements of different models are different, and the requirements for the highest and lowest tire pressure are also different. The requirements of the same tire installed on different models are different, so the optimal tire pressure is not a fixed value, but depends on different models. The standard tire pressure value of each model is marked in the user manual of the vehicle or in 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, and the temperature is hot in summer. It is suggested that the tire pressure should be reduced by 0. 1~0.2, and the temperature is relatively low in winter. It is suggested to increase the tire pressure by 0. 1~0.2, and the normal standard tire is 2.4-2.5bar. There are slight 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 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: According to the standard upper limit of full load vehicle tire pressure (the maximum tire pressure value on the tire label can be used as a reference for theoretical maximum tire pressure). If the tire pressure measured by hot car is normal, the tire pressure measured by cold car is slightly higher, which will directly affect fuel consumption. Tires are rubber products, which expand when heated and contract when cooled. Therefore, it is suggested that the air pressure of the four wheels should be around 2.3-2.4 when the car is cold, so that it is comfortable to run and saves fuel. Now the weather is getting hotter and hotter, there is no need to increase the tire pressure too high! The ideal tire pressure value of family car is 2.3-2.5, and the cold tire is 2.3 in summer, which will increase by 0. 1 after driving for a period of time. I hope I can help you. Please accept it if you are satisfied. If the cold tire pressure is a little high, after all, the tire pressure will rise a little when the temperature is high. It is suggested that the cold tire pressure should not exceed 250 this season. It is safer to take the cold test as the standard. The use and air pressure of cars and city SUVs and MPV tires: Let's discuss the air pressure in your manual first. At light load, the front wheel air pressure is about 2.2, and you will see that the tire is in a cold state, which is peaceful at this time. Personally, the original intention of the manufacturer is to improve the friction coefficient and comfort on mountain climbing, wading, sandy pavement, muddy pavement and icy pavement, and sacrifice the service life and energy saving of tires. But among users, who will use their cars as off-road vehicles? Ha, most riders drive on flat roads. 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
