What is the appropriate tire pressure value?
2 Answers
Tire pressure values represent the air pressure in the four tires, with the most commonly used unit being bar. Below are specific details about tire pressure monitoring: Direct Tire Pressure Monitoring: Direct tire pressure monitoring systems use pressure sensors installed in each tire to directly measure the tire pressure. The pressure information is then transmitted wirelessly from inside the tire to a central receiver module, which displays the pressure data for each tire. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that tire to become smaller, leading to a faster rotation speed compared to the other wheels. By comparing the differences in rotation speeds between the tires, the system monitors the tire pressure.
I've been driving for over 30 years, and tire pressure is something to be careful about. Generally, the tire pressure for small cars is between 32 and 35 PSI, but you should check the label on the door edge or the recommended value in the owner's manual. Too low pressure can increase fuel consumption, and more dangerously, it may cause a blowout at high speeds; too high pressure leads to faster tire wear and a bumpy ride. I now make it a habit to check with a tire pressure gauge every week, ensuring accurate measurements when the tires are cold and that the pressure is consistent between the front and rear tires. Seasonal changes have a big impact—tire pressure drops in winter due to low temperatures, so you need to add air; in summer, heat causes expansion and pressure to rise, so you need to let some air out. Don’t forget that regular checks can prevent air leaks, and safe driving relies on these details. Also, pay attention to the tire’s appearance—if there’s uneven wear, address it promptly. Don’t overlook these small things; they’re crucial for driving safety.
