What is the normal value for tire pressure monitoring?
2 Answers
The normal value for tire pressure monitoring is between 2.3 and 2.5 bar. The functions of tire pressure monitoring are: 1. It will promptly alert you in case of rapid or slow air leakage when the tire is punctured; 2. It will issue an alarm when tire loosening causes unbalanced friction, leading to tire temperatures reaching 70 degrees Celsius, thereby preventing tire blowouts; 3. It will alert you when the tire pressure falls below the vehicle's set limit due to prolonged lack of inflation, preventing low pressure from causing tire temperature rise and blowouts. The method to reset the tire pressure monitoring is: 1. Ensure the vehicle's tire pressure is within the normal range; 2. Park the vehicle on a flat surface and turn off the engine; 3. Power on the vehicle, press and hold the tire pressure monitoring button, and after 5 seconds, you will hear an alarm sound. Release the button to complete the reset successfully.
I always check tire pressure when the car is cold, as that's when the readings are most accurate. The standard range for sedans is 2.3 to 2.5 bar, while SUVs can be slightly higher at 2.5 to 2.8 bar. The exact values actually vary for each vehicle - I recommend checking the label on the driver's side door jamb where manufacturers clearly specify them. For example, German cars I've driven typically require 2.4 bar, while American pickups might need up to 2.8 bar. Overinflated tires will bulge and wear faster in the center, plus the steering feels floaty; underinflation increases fuel consumption dramatically and causes dangerous tire deformation during cornering. I always check pressure before highway trips - safety is no trivial matter. Seasonal changes matter too: pressure tends to drop in winter, while summer road trips may increase it by about 0.2 bar.
