What is the normal tire pressure display?
2 Answers
Tire pressure display of 2.4 to 2.5 bar is normal, but the specified tire pressure values vary for different types of tires. Tire pressure should be determined based on the season, driving conditions, and vehicle load. Typically, in winter, the tire pressure can be appropriately increased, while in summer, when temperatures are higher, the tire pressure can be reduced to prevent tire blowouts. Tire pressure refers to the air pressure inside the tire, which is an indicator of the vehicle's load capacity. The load capacity of the vehicle depends on the level of tire pressure. According to the relationship between the tire's load index, tire pressure, and load capacity, the higher the tire pressure, the greater the load capacity; the lower the pressure, the smaller the load capacity.
From my years of driving experience, the normal tire pressure range depends on the specific vehicle model and load conditions. Generally, the recommended tire pressure for sedans and SUVs is between 30 to 35 psi. In winter, cold air causes tire pressure to drop, while in summer, heat increases it, so it's best to check before the seasons change. I've made it a habit to measure the cold tire pressure with a tire gauge every week, avoiding measurements right after driving as they won't be accurate. If the pressure is too low, tire wear accelerates and fuel consumption increases; if it's too high, comfort is affected, leading to a bumpy ride. When the Tire Pressure Monitoring System (TPMS) in modern cars lights up with a warning, it's time to act quickly to avoid the risk of a blowout. I recommend referring to the label on the edge of the car door or the owner's manual, as these are the most reliable sources of information—don't trust online guesses. The first step to safe driving is maintaining proper tire pressure; neglecting this can lead to unnecessary repairs and accidents.
