What is the appropriate tire pressure?
2 Answers
Tire pressure between 2.3 to 2.8 bar is appropriate. Tire pressure refers to the air pressure inside the tire. Hazards of excessive tire pressure: 1. The friction and adhesion of the tire will decrease, affecting braking performance; 2. It may cause steering wheel vibration and deviation, reducing driving comfort; 3. Accelerates wear on the central tread pattern, shortening tire lifespan; 4. Increases vehicle vibration, indirectly affecting the lifespan of other components. Factors affecting tire pressure: 1. Seasonal factors: In winter, it's advisable to increase the standard tire pressure by 0.2 bar, while in summer, if the vehicle is parked outdoors, the pressure can be 0.1 bar lower than the standard to prevent blowouts due to high temperatures; 2. Tire pressure measurement environment: Cold tires and hot tires have different pressures, with a typical difference of 0.3 bar that should be noted during measurement.
Tire pressure is something I think is best kept within the 32 to 35 PSI range, but it really depends on what car you drive. I've driven quite a few cars, and generally, for sedans, 32 PSI in the front and 34 PSI in the rear works well, while SUVs might need slightly higher. Remember to check when the tires are cold, like first thing in the morning, for the most accurate reading. If the pressure is too low, the tires can deform, wear out faster, or even blow out, especially at high speeds. Too high, and the ride gets bumpy and fuel efficiency drops. I recommend checking the label on your car door frame or the owner's manual for the manufacturer's exact recommendations. I make it a habit to check every two weeks with a simple pressure gauge. Seasonal changes matter too—add 1-2 PSI in winter and maintain normal levels in summer. In short, regular maintenance not only saves trouble but also extends tire life—don't overlook it.
