What is the normal tire pressure in kPa?
2 Answers
Tire pressure is generally considered normal between 230 to 250 kPa. If the car is fully loaded (5 people), it's more suitable to adjust the tire pressure to around 2.5 bar; for two passengers, a tire pressure of 2.3 bar is also normal. Tire pressure refers to the air pressure inside the tire. In car maintenance, the engine is the heart of the car, and damage to the engine can lead to the end of the car's life. The 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. Tire pressure is an indicator of the car's load capacity, and the size of the car's load depends on the level of tire pressure.
I pay close attention to tire pressure, which normally ranges between 180 to 250 kPa depending on your vehicle. The recommended value is usually marked on the door jamb or in the owner's manual—for my car, it's 220 kPa. Seasonal changes matter too: in winter, I add about 5 kPa for cold resistance, while in summer, I reduce it slightly to prevent blowouts. I've made it a habit to check monthly when tires are cold using a simple pressure gauge. Underinflation accelerates tread wear and affects handling, while overinflation makes rides bumpy and wastes fuel. Once, I neglected it for weeks and ended up with uneven wear, costing me extra for premature replacements. Now, regular checks keep me safe and save money.
