What is the normal air pressure for a car's front tires?
2 Answers
The normal air pressure for a car's front tires ranges from 2.4 to 2.8 bar. The functions of tires are: 1. Transmitting driving force, braking force, and steering force to achieve vehicle control; 2. Supporting vehicle load; 3. Reducing and absorbing vibrations and impacts during driving to avoid severe vibrations damaging vehicle components. Car tire maintenance methods include: 1. Regularly checking tire pressure; 2. Removing debris from tire treads; 3. Inspecting tire wear and replacing them promptly based on wear conditions; 4. Performing wheel rotation to ensure even force distribution and prevent excessive wear.
As an experienced driver who has been driving for many years, I think the normal tire pressure for the front wheels of a car is around 230 to 250 kPa. This value is usually based on the manufacturer's recommendation on the door sticker—my own car says 240 kPa. I make it a habit to check the tire pressure once a month with a tire pressure gauge, preferably when the tires are cold, as the pressure increases with temperature and can be misleading. If the pressure is too low, it not only increases fuel consumption but also makes the car unstable when turning. If it's too high, the center of the tire wears out faster, and the ride becomes uncomfortably bumpy. From experience, if the car is heavily loaded, you can increase the pressure by about 10 kPa, but don’t exceed the upper limit of 25 kPa. In summer, when it's hot, the pressure expands more, so be mindful of reducing it slightly. In winter, when it's cold, the pressure drops, so you may need to add a bit. Developing a habit of regular checks is simple—just use a tire pressure gauge that costs a few dozen bucks, ensuring safety and peace of mind.
