What does low tire pressure mean?
3 Answers
Tire low pressure means that the tire pressure is too low. When this situation occurs, it should be inflated in time. The following is the extended information: 1. When the tire pressure is too high or too low: The tire pressure should not be too high or too low. If the pressure is too low, the tire will show wave deformation during high-speed driving, which will reduce the service life of the tire and also increase the chance of a tire blowout. If the pressure is too high, it will reduce the contact area between the tire and the ground, which will affect the car's handling and driving stability. 2. Tire replacement time: Tires are rubber products, and rubber products will age after long-term use, so tires are a vulnerable part that needs to be replaced regularly. Generally, tires need to be replaced every four years, so it is recommended to replace the tires every four years. When buying new tires, be sure to check the production date clearly, as tires also have a shelf life. Generally, the shelf life of unused tires is three years. If the tires have been produced for more than three years, do not purchase them.
I've been driving for over a decade, and low tire pressure means the tires don't have enough air, with the pressure lower than the manufacturer's recommendation. It's quite common, like when there's a leak, the tires age, or when the temperature drops suddenly, causing the air to contract and leading to low pressure. I've personally experienced it – driving with low pressure makes the car feel heavy, the steering wheel stiff, and the fuel consumption shockingly high. Once on a long trip of several hundred kilometers, my fuel consumption increased by 15%, and later I found out the tire pressure was only 20 psi when the standard is 32 psi. What's even more dangerous is the reduced handling, longer braking distances, and the increased risk of losing control during high-speed turns. The tires also wear unevenly, with the inner edges wearing out faster, which over time could lead to a blowout. I recommend everyone buy a compact tire pressure gauge and check all four tires once a month, keeping them at the value on the door label when the car is cold.
As a car enthusiast who often helps friends with car repairs, low tire pressure refers to the condition where the internal air pressure of a tire is insufficient. There are many reasons for this: first, slow leaks, such as small nails in the tire or damaged valve stems; second, significant temperature changes, as tire pressure can drop by 1-2 psi in cold weather; third, wheel rim deformation or sealing issues. Low pressure is no small matter—it increases the tire's contact patch with the road, raising friction and causing overheating, which accelerates tire aging. I once disassembled a low-pressure tire and found the inner cords deformed, posing a huge hidden danger. It's advisable to pay attention to the tire pressure monitoring system (TPMS) light during daily use—it serves as a warning signal when illuminated. If you prefer a hands-on approach, use a standard tire pressure gauge to check every two weeks and top up according to the manual's recommended PSI value. Don’t forget to adjust the pressure seasonally—slightly higher in summer to prevent blowouts.
