What to Do When Tire Pressure is Lost?

Tire pressure loss requires checking whether the tire pressure sensor is damaged or simply needs to be reset. It is recommended to visit a repair station for a tire pressure check. Strictly speaking, tire pressure refers to the air pressure inside the tire. In terms of car maintenance, the engine is the heart of the car, and damage to the engine will lead to the end of the car's life. Tire pressure is the blood pressure of the car, and the level of tire pressure plays a crucial role in the car's performance and power. Low air pressure will increase the deformation of the tire body, making the tire side prone to cracks, while also causing flexing movements, leading to excessive heat, promoting rubber aging, fatigue of the cord fabric layer, and breakage of the cord. It will also increase the tire's contact area with the ground, accelerating wear on the tire shoulders.

I just experienced a tire pressure loss last week while driving to the countryside. After hearing a hissing sound, I immediately slowed down and gradually moved the car to the emergency lane with hazard lights on, then placed a warning triangle. When I checked with the tire pressure gauge from the trunk, it showed only 1.0 bar—luckily the spare tire was fully inflated. While changing the tire, I found a nail had punctured the sidewall, which is unrepairable and required a new tire. A reminder to everyone: regularly check your spare tire's pressure, and it's best to keep a portable air pump in the car. If you're inexperienced with changing tires, stay in a safe spot and call for roadside assistance. Driving on a flat tire can damage the wheel rim and is extremely dangerous.

I have experience with tire pressure loss, and safety is the top priority. When the tire pressure warning light comes on, avoid slamming on the brakes to prevent losing control of the steering wheel. Drive steadily to a safe area, as if holding a bowl of water. Most modern cars are equipped with a Tire Pressure Monitoring System (TPMS), but the warning threshold is typically a 25% or greater drop in pressure, so it's essential to manually check tire conditions regularly. Tire sealant can handle small punctures, but for larger cuts, you'll need to switch to the spare tire. Never use the spare tire for an extended period, and adhere to the speed limit of 80 km/h. Lastly, remember that sidewall damage requires immediate replacement, and if a tire has been repaired in more than three places, it's advisable to replace it to ensure safety.

There are several situations of tire pressure loss: slow leaks can still be driven to a repair shop, but a flat tire requires immediate stopping. Last week, while taking my child to school, the tire pressure warning light came on. I drove slowly to the repair shop and found it was due to a leaking valve stem caused by aging. Key points about spare tire usage: never use a non-full-size spare tire for long-distance driving; exceeding 50 kilometers can damage the suspension system. There are two types of tire repairs: hot patching and cold patching. Mushroom plugs can fix holes up to 6mm. Remember to check tread depth monthly using a coin; replace the tire when the wear reaches the 1.6mm indicator.
