Should the front and rear tire pressures of a car be the same?
2 Answers
If both are around the standard tire pressure, the front and rear tire pressures can be different. The tire pressure check cycle and precautions for checking tire pressure are as follows: Tire pressure check cycle: Generally, car tire pressure should be checked at least once a month. Pay attention to adjusting the tire pressure during each seasonal change, with the ideal adjustment times being November and May. In November, as winter approaches, tire pressure usually drops and should be slightly adjusted. Precautions for checking tire pressure: In May, as the weather starts to get hotter, it is recommended to check if the tire pressure is normal. Special attention should be paid to the fact that as long as the tire pressure is not significantly higher than the standard range, there is no need to deliberately reduce the tire pressure. If the tires are not under-inflated, there is no need to adjust them every month.
I've been driving for over ten years, and at first, I also thought the tire pressure should be the same for both front and rear tires. But later, I realized that was completely wrong. For example, with my old sedan, maintaining the same tire pressure was fine for daily commutes. However, during my last road trip with a fully loaded trunk, the rear tires were noticeably flatter, fuel consumption increased significantly, and the handling felt unstable. When I took it to the mechanic, he told me that for this type of car, the rear tire pressure should be about 0.2 bar higher than the front to balance the car's weight for better safety. Now, I always check the recommendations on the door label or the owner's manual instead of just inflating based on feel. Regular checks are also crucial. I keep a tire pressure gauge handy and measure it monthly to avoid the risk of a blowout—saving money and giving me peace of mind.
