Is a tire pressure of 1.9 normal?
2 Answers
A tire pressure of 1.9 is not normal; it is too low. The normal tire pressure should be between 2.2 and 2.5 bar. The effects of low tire pressure include: 1. Damage and abnormal wear to the tire bead area, reducing tire strength and increasing the risk of blowouts during high-speed driving; 2. Increased movement in various parts of the tire, leading to excessive rolling and abnormal heat generation, which can damage the tire bead area and cause abnormal wear; 3. A significant increase in friction with the ground, causing a sharp rise in tire temperature, softening of the tire, and a rapid decrease in strength. Methods for tire maintenance include: 1. Regularly removing debris from the tire tread; 2. Checking tire wear and replacing tires promptly; 3. Periodically checking tire pressure; 4. Repairing tires in a timely manner.
A tire pressure of 1.9 is definitely abnormal. I usually keep an eye on the dashboard while driving, and normal tire pressure should be at least between 2.2 and 2.5. Yours is clearly too low. If you drive like this for a long time, the tire wear will be much faster, and the sidewalls are prone to bulging and cracking. It's even more dangerous if you run over a nail. Moreover, the steering wheel will become very heavy, and fuel consumption will increase significantly. Once, when my tire pressure dropped to 2.0, it consumed an extra liter of fuel per 100 kilometers. It's best to check the tire pressure when the car is cold and immediately inflate it to the manufacturer's recommended value, which can be found on the door frame sticker or in the manual. After inflating, remember to check again for slow leaks, and also test the spare tire while you're at it.
