What is the appropriate tire pressure?
2 Answers
There are two scenarios for appropriate car tire pressure: 1. The front tire pressure should be 2.2 to 2.3 bar when unloaded and 2.4 to 2.5 bar when fully loaded. 2. The rear tire pressure should be 2.4 to 2.5 bar when unloaded and 2.6 to 2.8 bar when fully loaded. The recommended tire pressure range may vary depending on the tire model, and the standard tire pressure is usually indicated by the manufacturer at the time of production. Tire pressure can also be affected by temperature changes. In high temperatures or during summer, it is advisable to reduce the tire pressure by 0.1 to 0.2 bar. Conversely, in extremely low temperatures, such as during winter, it is recommended to increase the tire pressure by 0.1 to 0.2 bar.
I think tire pressure is quite important. The reference values are usually found on the label inside the door frame or in the owner's manual. For small cars, it's typically around 30-35 PSI, while SUVs may require a slightly higher pressure of 35-40. If the pressure is too high, the tire's grip decreases, making the ride bumpy, and it can also lead to excessive wear in the center. On the other hand, if the pressure is too low, fuel consumption increases and there's a risk of a blowout. I make it a habit to check the pressure once a month using a home pressure gauge when the tires are cold for the most accurate reading. Temperature changes can significantly affect tire pressure. In summer, prolonged downhill driving can cause heat expansion and overpressure, while in winter, cold contraction may lead to lower pressure, so remember to adjust it when seasons change. Maintaining the correct tire pressure not only ensures safety and fuel efficiency but also extends tire life. Don't overlook this small detail, as driving hazards often stem from negligence.
