What is the optimal standard for car tire pressure?

2.3-2.5 bar is the most suitable. Introduction to tire pressure: Tire pressure, strictly speaking, refers to the air pressure inside the tire. In car maintenance, the engine is the heart of the car, and its damage will lead to the end of the car's life. Similarly, tire pressure is the blood pressure of the car, and the level of tire pressure plays a crucial role in the performance and power of the car. Effects of excessive tire pressure: Driving with excessively high tire pressure will reduce the tire's shock absorption effect, thereby increasing the burden on the vehicle's shock absorption system. Over time, it will cause damage to the engine chassis and suspension system. Uneven tire pressure can also easily cause braking deviation, increasing the wear on the suspension system. TPMS (Tire Pressure Monitoring System) can monitor any tire at any time, preventing the above phenomena and reducing the wear on the suspension system.

I've been driving for over a decade, and tire pressure is something you really need to pay attention to. The optimal standard is usually around 220 to 240 kPa, depending on the vehicle model. There's a label on the door frame or in the driver's manual that indicates the recommended pressure—my old car specifies 230 kPa. If the pressure is too high, the ride becomes bumpy and uncomfortable, and there's a higher risk of a blowout; if it's too low, the tires wear out faster and fuel consumption increases. I recommend checking it monthly with a simple pressure gauge. Temperature changes also affect tire pressure—in winter when the pressure drops, you should top it up, and in summer when the pressure rises, you can release some air to keep it within the correct range, ensuring safer and more comfortable driving.

Check the tire pressure of your car, with the ideal value typically around 32 to 35 pounds per square inch (PSI), depending on the vehicle weight and tire type. Specific values can be found on the door pillar or in the manual. I would emphasize using a proper pressure gauge for accurate measurement, as deviations exceeding 10% may cause issues. Incorrect tire pressure can lead to irregular tire wear, affect braking distance, and even pose a risk of losing control. For maintenance, don't rely solely on gas station equipment; bringing your own gauge is more reliable. Professional shops also offer free inspection services. Remember to measure when the tires are cold for accuracy, avoiding measurements right after driving.

When I first started driving, I was also confused about the tire pressure. After checking the user manual, I learned that cars usually require between 32 to 35 psi, but it varies for each vehicle. I bought a simple tire pressure gauge myself and check it in the morning when the car is cold, keeping it at the recommended value. Low pressure makes the steering wheel heavy and increases fuel consumption, while high pressure makes the car feel unstable when driving. Simple tip: check the sticker on the door before driving and get a gauge to measure it.
