In daily life, we often only stay on the surface of car maintenance, such as body cleaning, oil change, etc., but often ignore a vital link - tire pressure. Some netizens asked, why can't the tire pressure be adjusted at will? What is the tire pressure standard for different models? This article will unravel these mysteries for you.
The importance of tire pressure cannot be overstated. Tire pressures that are too high or too low can pose a threat to driving safety. Low tire pressure will cause excessive deformation of the contact part of the tire with the ground, resulting in a sharp rise in tire temperature, which may lead to the rupture of the tire shell and increase the risk of puncture. Moreover, too low tire pressure will also increase the air leakage of the tire itself, affecting driving safety. In contrast, although high tire pressure can reduce the contact area between the tire and the ground, reduce frictional resistance, and thus reduce fuel consumption, it will also increase tire wear and shorten its service life.
So, how do you determine the tire pressure standard of your own vehicle? Most manufacturers of family cars will indicate the recommended tire pressure in the vehicle owner's manual, near the B-pillar of the cab door, and in the vehicle's fuel tank cap. Generally speaking, the recommended tire pressure for a family car is 21~2.3bar. For example, the Nissan Sylphy has a front and rear tire pressure of 23bar and 21bar；The Corolla has a front and rear tire pressure of 23bar；The front and rear tire pressures of the Honda CRV are both 21bar。
However, for electric vehicles, due to the high body weight, the manufacturer's recommended tire pressure standard will also be increased accordingly. Tesla, for example, has a recommended tire pressure of 2 for most of its models9~3.1bar。In addition, car owners can also understand real-time tire pressure data through the vehicle's dashboard or tire pressure monitoring system to ensure driving safety.
