What is the situation with the car tire pressure warning?
2 Answers
Car tire pressure warning occurs due to the following reasons: 1. Air leakage from the tire or valve; 2. Wheel hub deformation leading to reduced tire sealing performance; 3. Long-term overloading of the vehicle causing uneven tire stress; 4. Thermal expansion and contraction resulting in insufficient tire pressure. Tire pressure refers to the air pressure inside the tire, with a normal monitoring range between 2.2 and 2.5 bar. Methods for monitoring tire pressure include: 1. Direct tire pressure monitoring; 2. Indirect tire pressure monitoring; 3. Using a smart tire monitoring system for detection. The impacts of low tire pressure are: 1. Increased contact area between the tire and the ground, leading to abnormal tire temperature; 2. Severe deformation of the tire sidewall, accelerating the aging of internal steel wires and fabric layers, which may cause a blowout; 3. Increased fuel consumption; 4. Reduced tire lifespan.
The other day while driving, I saw the tire pressure warning light flash on the dashboard and got nervous for a while before figuring it out. This usually alerts you when the tire pressure is too low or too high, as the system sensors detect abnormal pressure, such as a leak causing slightly low pressure. Temperature drops can also reduce pressure, or a nail puncture might cause a slow leak. Quickly slow down and pull over safely, then use a tire pressure gauge to check each tire’s pressure to see if it’s below the standard value (often listed as the recommended value on the door frame). If it’s low, head to an air station to refill. Insufficient tire pressure not only accelerates wear and makes handling unstable but also increases the risk of a dangerous blowout. Make it a habit to check tire pressure monthly—it’s safer and improves fuel efficiency. Pay extra attention in cold weather, and don’t wait for the warning light to panic.
