Is a tire pressure of 1.9 bar already indicating air leakage?
2 Answers
A tire pressure of 1.9 bar could be due to a puncture causing air leakage, which naturally results in lower tire pressure. If the low tire pressure is caused by a puncture, the tire should be repaired or replaced as necessary, and then the tire pressure should be adjusted to the standard level. Under normal circumstances, the tire pressure of a car should be between 2.3 and 2.5 bar. Hazards of too high or too low tire pressure: For tires, the pressure should neither be too high nor too low. Excessive tire pressure reduces the contact area between the tire and the ground, leading to poor grip, which affects the car's handling and driving stability. Insufficient tire pressure can cause wave-like deformation during high-speed driving, affecting the tire's lifespan and increasing the risk of a blowout. Introduction to standard tire pressure: According to the international GBT2978-2008 standard, the recommended tire pressures are as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; Maximum pressure: should not exceed 3.5 bar.
I've been driving for over 20 years, and a tire pressure of 1.9 bar is definitely too low. The normal range should be between 2.0 and 2.5 bar. Such a low reading likely indicates a leak. I remember last year when my own car's tire pressure dropped to 1.8 bar, I found a small nail puncture that was slowly leaking air. If I hadn't inflated and repaired it in time, the tire wear would have accelerated, and there would have been a higher risk of a blowout at high speeds. I suggest you don't take it lightly—use a tire pressure gauge to check the other tires immediately. If they're all low, it might be due to temperature changes, but if there's a noticeable drop, you should visit a repair shop to check for leaks. Make it a habit to check your tire pressure once a month—it's both safe and worry-free.
