What to Do If the Tire Pressure Is Too High?

Solutions for excessively high tire pressure: 1. If you are using a pointer-type tire pressure gauge, when you find that the tire pressure is too high, you can directly press the deflation valve while observing the numbers on the gauge to maintain normal tire pressure; 2. If there is no dedicated deflation valve, you can only use a valve core wrench or a fine-pointed object like a pen to press against the valve core, and then slowly release the air. After manually deflating, you should check whether the tire pressure is normal. If it has reached the appropriate range, be sure to remember to install the valve cap tightly to prevent dust and debris from entering the valve core. After inflating, you can apply soap foam to the valve to check for leaks. If there is a leak, continuous small bubbles will appear.
I noticed the tire pressure warning light came on while driving on the highway. After pulling over and checking, the pressure had skyrocketed to 3.0 bar! I quickly grabbed the tire pressure gauge from the car's toolkit and began deflating each tire. Remember to adjust the pressure when the tires are cold, releasing 0.1 bar at a time and checking after each adjustment. It took me twenty minutes to bring it down to the standard 2.3 bar. This incident reminded me not to let gas station attendants randomly inflate my tires during car washes—last week they pumped them up to 3.2 bar in one go. Overinflated tires not only make the ride bumpy but also increase the risk of skidding in wet conditions, and worst of all, they can blow out when hitting potholes. I recommend using a mechanical tire pressure gauge to check monthly—it's much more accurate than the car's built-in sensors.
When repairing cars, I often see vehicles with severely worn-out tire centers, and nine times out of ten, it's due to excessive tire pressure. The consequences of long-term driving at 3.0 bar are no joke—tire contact area is reduced by 30%, and braking distance can increase by over half a meter. When handling this, remember to have a bucket of cold water ready to cool the tires, and operate the deflation valve while cooling. If you don’t have a tire pressure gauge, don’t panic—most gas stations have free inflation equipment with pressure gauges. The most crucial step is to find the manufacturer’s standard value, which is sometimes on a sticker on the front door frame or in the manual for older cars. Never believe the myth that tires should feel harder when driving—if the pressure exceeds 0.3 bar, it should be addressed immediately.
