Is a tire pressure of 1.9 normal?
2 Answers
A tire pressure of 1.9 is not normal and should be inflated as soon as possible. Low tire pressure increases the contact area between the tire and the ground and causes severe deformation of the tire sidewall. Generally, the recommended tire pressure for car tires is around 2 to 2.5 bar. According to the principle of thermal expansion and contraction, in summer, the tire pressure can be adjusted 0.1 to 0.2 bar lower than the normal value, while in winter, it can be adjusted 0.1 to 0.2 bar higher. When inflating tires, pay attention to the following: 1. Always use a pressure gauge to check the pressure to avoid over-inflation, which may cause the tire to burst; 2. After stopping the vehicle, wait for the tire to cool down before inflating; 3. If the valve stem and valve core do not fit properly, it will be inconvenient to inflate or measure the pressure; 4. The air being pumped in should not contain moisture or oil.
Hi, let me share some insights on tire pressure from experience. A tire pressure of 1.9 bar sounds a bit low, as the normal range is around 2.0 to 2.5 bar, depending on your specific car model. I recall the recommended values are listed in the owner's manual, and there's usually a small sticker on the door frame indicating them as well. Low tire pressure makes the tires softer, leading to unstable handling, potential tail swing during turns, and longer braking distances. Not to mention the safety risks—uneven tire wear over time can cause blowouts or leaks, especially during long trips or on wet roads. There's also the fuel consumption issue; insufficient pressure increases rolling resistance, wasting gas unnecessarily and costing you extra money over a year. I suggest you grab a tire pressure gauge and check it ASAP. Self-service air pumps at gas stations are quite convenient. Make it a habit to check monthly—maintaining proper pressure extends tire life and reduces repair hassles.
