What is the solution when the tire pressure warning light stays on?

The solution when the tire pressure warning light stays on is: pull over to check the tire pressure, inflate if the pressure is low, release air if the pressure is high, and promptly replace with a spare tire if there is an issue with the tire. The hazards of excessive tire pressure include: 1. Reduced friction and adhesion of the tire, affecting braking performance and tire lifespan; 2. Decreased puncture resistance, increasing the risk of a blowout; 3. Accelerated wear on the central tread pattern, shortening tire lifespan, increasing vehicle vibration, and affecting the longevity of other components; 4. Excessive stretching and deformation of tire cords, reducing tire elasticity, increasing the load on the vehicle while driving, and decreasing puncture resistance; 5. Increased susceptibility to punctures from nails, glass, and other sharp objects on the road, leading to internal cracks and blowouts under impact.

I usually drive to and from work, and the most annoying thing is when the tire pressure warning light stays on. I encountered this issue last time, and it took me a long time to figure it out. Generally, it could be due to low tire pressure or a faulty system sensor. The solution is quite simple. The first step is to use a tire pressure gauge to check the pressure of each tire—the standard values can be found on the door frame or in the manual. If the pressure is low, use an air pump to inflate them. If the light remains on after inflating, try pressing the reset button in the car, usually located near the steering wheel or on the dashboard. If the light comes back on after resetting, the sensor might be broken, and you’ll need to visit a 4S shop for professional diagnostics. Additionally, tire pressure tends to drop in cold weather, so it’s important to check more frequently in autumn and winter. Don’t try to fix it blindly—if something goes wrong with the tires while driving, it could be a serious problem. Last winter, I forgot to check, and one tire ended up leaking, nearly causing an accident. Now, I’ve made it a habit to check the tire pressure every month.

As a new driver, seeing the tire pressure warning light constantly on can be really nerve-wracking. I often help my friends deal with this now. The first step to solving it is to stay calm and don't rush to the repair shop. First, check all four tires for obvious leaks, like nails stuck in them or severe wear. If there's none, buy an inexpensive tire pressure gauge to measure the pressure yourself—it's usually most accurate when the car is cold. If the reading is low, fill them up at a gas station air pump. Then, check the manual to find the tire pressure system reset button, hold it for a few seconds, and the light should turn off. If it stays on, it means there's an internal sensor malfunction—don't force it, just go to a nearby shop to replace the part. If you don't fix this promptly, the tires will wear out faster, fuel efficiency will drop, and worse, there's a high risk of a blowout on the highway. I just learned this method last month and saved over 500 bucks in repair costs. Safety-wise, if the light stays on, it's a warning signal—never delay. Park in a safe spot and check the manual again.

With over a decade of car experience, I've found most tire pressure warning lights are caused by false alarms. Systematic troubleshooting is key. Checking pressure is crucial - standard range is typically 2.2 to 2.5 bar. The light may activate if pressure is too low or high, and mechanical gauges are more accurate than digital ones. After inflation, reset the system by holding the steering wheel button for 3 seconds. If that fails, consider dead sensor batteries or signal interference, especially on cars with modified rims. I recommend keeping an OBD scanner (available online for about $10) to read error codes yourself. For persistent issues, visit a professional shop - sensor replacement is affordable but requires matching the correct model. Avoid parking on gravel roads to minimize vibration damage. Sudden temperature changes may also trigger false alerts (like low morning pressure in summer), which usually resolves after restarting. While not a major issue, address warning lights promptly to prevent minor problems becoming costly repairs.
