At what pressure below the standard 240 should tires be inflated?

Generally, the normal value is around 2.3-2.5. If the tire pressure is below this range, you should inflate your tires to avoid accidents and mishaps. In addition to knowing your standard tire pressure, you should also consider these important factors: Seasonal factors: In winter, adjust the tire pressure slightly higher by about 0.2 bar based on the standard tire pressure. In summer, follow the lower limit of the standard tire pressure. Load capacity: When the vehicle is empty, follow the lower limit of the standard tire pressure (the tire pressure indicated on the vehicle's sticker can serve as a reference for the minimum tire pressure). When fully loaded, follow the upper limit of the standard tire pressure (the maximum tire pressure indicated on the tire can serve as a reference for the theoretical maximum tire pressure).
Low tire pressure can lead to many hidden dangers. I often help out at maintenance stations and see many car owners neglecting this issue. The standard tire pressure is 240 kPa, and if it drops below 216 kPa, it's recommended to inflate the tires immediately—this is roughly a 10% decrease. Why? Insufficient pressure causes greater tire deformation, increases rolling resistance, and immediately raises fuel consumption. Driving long-term with low pressure can also lead to uneven tire wear and even increase the risk of a blowout. It's best to check tire pressure when the car is cold to avoid errors caused by temperature. I usually recommend using a tire pressure gauge once a week to top up the air promptly. This not only ensures safer driving but also helps you save on fuel costs. Don’t underestimate this detail—once you make it a habit, you’ll notice your car drives more smoothly and effortlessly.
